A caster is an assembly that consists of a non-powered wheel and a mount. Generally, caster wheels support and make it easy to maneuver shopping carts, office chairs, and medical beds, among other equipment. Moreover, they are available in numerous designs based on operational requirements, providing mobility options for a wide range of applications.

The applications that utilize caster wheels require precise sizing to accommodate the terrain on which they will be used and the weights they are expected to carry. For instance, heavy loads need casters with thicker wheels, and larger objects need multiple wheels to evenly distribute the loads. Furthermore, caster wheels can be made using varying manufacturing processes, two of which we will outline below.

Metal Plate Cutting Process

In this process, the top plate is cut first. This plate is used to mount the caster underneath the object. To begin, a thick sheet of steel is cut by a CNC, a thermal cutting technique that takes advantage of an ionized gas to cut metal. Instead of mechanically cutting into the metal, this technique uses heat to melt the metal. Then, the fork element is cut.

Usually made of steel coil, forks are the arms that hold each side of the wheel axle. The steel coil is rolled out and fed into a punch press machine which breaks it with the yoke shaped dye. Moreover, the broken yoke shaped pieces are situated onto a forming press that bends the piece into the desired shape and makes a circular groove around the hole in the center.

At this point, the hole is filled with steel ball bearings that enable the yoke to swivel. A steel retainer is fitted to keep the bearings in place, while the grooves of the steel cap are filled with ball bearings. The cap is placed onto a punch press with the yoke on top. The press affixes the cap to the yoke’s retainer, so that the ball bearings are wedged in between. Once the top plate has been riveted to the yoke, a steel seal must be put over the retainer and locked into position with a pneumatic press.

Rubber or Nylon Extrusion

The next machining process is accomplished through the extrusion of the wheel material. First, nylon inserts are placed in an injection molding press that melts the neoprene rubber and injects it into the mold. Once cooled to a solid state, the machine ejects rubber wedged wheels which are capable of absorbing shock, reducing noise, and preventing damage to the floor or surface.

Types of Caster Wheels

There are a few common types of caster wheels, some of which we will cover in this section.

Cast Iron and Semi-Steel Caster Wheels

Typically made of gray iron, cast iron and semi-steel caster wheels are abrasion-resistant and long-lasting. They necessitate little effort to start rolling and are designed for high-capacity applications. Additionally, these wheels operate well in environments exposed to mild chemicals or in oily and greasy areas.

Ferrous Wheels

Equipped with the highest load capacity, impact resistance, temperature range, and rollability when compared to their counterparts, ferrous wheels are often go-to choices for many applications. Their durable, solid structure is composed of forged steel or cast iron, making it ideal for harsh conditions such as those found in warehouses and manufacturing facilities.

Pneumatic Caster Wheels

Pneumatic caster wheels are made of rubber that has been filled with air to provide ample floor protection. With the capacity to roller over diverse obstacles, pneumatic caster wheels have a wide mobile range over many floor surfaces.

Other Common Types:

  • Flanged Caster Wheels
  • Forged Steel or Ductile Steel Caster Wheels
  • Glass Filled Nylon Caster Wheels
  • Hard Rubber Caster Wheels
  • Polyolefin Caster Wheels

When managing an aircraft or a fleet of such vehicles, one may find that purchasing and sourcing parts can be one of the more difficult aspects of overall operations. That being said, procurement does not have to be a challenge, and having an understanding of how to be properly organized can make the process much simpler. This is not to say that planning, processing, chasing, and tracing are not all individually important, but that they all must be carried out in an organized fashion to ensure little to no hiccups or stalls along the way.

When one considers the typical day for an aircraft parts buyer, it is easy to understand how the position can be quite hectic as internal and external demands always arise. While colleagues may charge you with creating and placing orders, you will also have to handle order fulfillment, supplier questions, canceled orders, payment requests, and much more. With a variety of roles that need to be executed simultaneously, organization is the key for avoiding frustration, stress, and loss of time. To ensure that you best utilize your resources, skills, and time, you need to establish a strategy and follow through.

As the first step of formulating an effective purchasing strategy, you should create an end-goal of some sort. This can be an objective of finding the lowest cost for a part, or primarily being concerned with how fast it can be delivered upon payment. Depending on this end-goal, the steps toward reaching it will greatly differ, making it important to create this end before moving forward. As an example, if you want to work with a reputable operator who can get you parts in five days, the desired element of getting parts fast is already set in stone, and the concerns of cost will come through reverse engineering.

You could try to shop around with multiple vendors, but that has its own drawbacks such as creating roadblocks and pauses as more and more choices have to be considered. The more people you contact will also increase the amount of emails, messages, and phone calls you have to handle, increasing your workload and stress. While some individuals may find this to be perfectly fine, others may find that the great increase of deal management can actually detract from the original goal of saving time or money. As such, thinking through the process that you may have to undertake, as well as the various roadblocks you may face, can help you have a much more solid plan to achieve the end goal that you originally set out for yourself.

One way to make your procurement duties easier is to develop a relationship with a reputable distributor that can bring you a balance of all your time and cost needs, allowing you to save time and money with ease. Additionally, building a relationship with distributors can help you avoid always having to do research for each order, as you will already have a reliable source that you can trust for fulfilling all your various requirements.

Valves are devices that serve the purpose of regulating the flow of a fluid, which may either be in the liquid or gas phase. With numerous design and size variations, it is helpful to understand which valve type works best for a given application. In the aviation industry, in particular, ball valves have become an integral component in vessel construction due to their long service lives and precise control capacity. In this blog, we will discuss the several nuances associated with ball valves and their use in the aerospace industry, highlighting their function and design variants.

Like many other valves, the ball-type sits inside a valve housing, which contains and protects the functional components. Extending from the top of the housing to the bottom is a valve stem, which is operated by either electrical or pneumatic means. Connected to the valve stem is the ball, which is supported by a specialized seat and o-rings. Most commonly, the stem is designed to operate with quarter turns, either permitting or preventing media flow with each.

Although 3-way and 4-way ball valves may be used in some circumstances, the overwhelming majority only feature two ports, particularly in aerospace. For most applications, the valve is manually operated by a user through the use of a lever, although some are fitted with an internal transmission. In general, when the lever is in line with the pipe, the ball allows media to flow, with the opposite being true if the lever is perpendicular. In the case of a 3-way valve, the bore will be manufactured in an L- or T-shaped manner, allowing the user to control media flow and direction.

Depending on operating environment demands, the housing may either be one-, two-, or three-piece. The one-piece assembly is the cheapest and most lightweight, but it is less durable and cannot be disassembled to be cleaned. As a result, they are typically reserved for low-output applications. Two-piece housings are commonly threaded and may be disassembled to support maintenance operations. Finally, the three-piece bolted housings are the most durable and simplest to remove for cleaning. Because of these factors, the three-piece variant is also the most expensive.

If the valve does not rely upon a lever or other twisting mechanism in its operation, it is considered to be automatic. These devices instead utilize an electric or pneumatic actuator to manipulate the valve stem. Such configurations allow for energy conservation and act as a fail-safe mechanism. Higher performance actuators can even provide modulation control, which enables the user to choose a precise level of opening.

In the aerospace industry, ball valves are implemented to accomplish precision fluid control. The most common media types transported are hydraulic fluid, water, coolant, and fuel. One place in particular where ball valves shine is turbines, where they are explicitly designed to handle the high-pressure and high-temperature environment. Another benefit of ball valves is their lower purchase cost and much longer lifespan compared to other designs. When choosing a ball valve for aerospace applications, it is important to select a reliable distributor such as ASAP NSN Hub.

Without a robust network of ground team members and equipment, aircraft would not be able to perform any operations. With air travel as busy as ever, planes may fly routes over ten times per day. In fact, it is not uncommon for a commercial aircraft to support 24-hour operations, covering thousands of miles and transporting hundreds of occupants in that given period.

While most of the magic in aviation occurs in the air, an equally critical time is when the vessel is on the ground. It is here where inspection takes place, the aircraft is refueled, waste is drained, and other necessary actions are carried out to get the plane ready for its next journey. The various tools used to support such operations are called ground support equipment (GSE), and like everything else in aviation, interested parties are constantly looking for ways to improve operations. In this blog, we will discuss airport utility pit systems, which are being implemented at hubs worldwide to bolster the capabilities of ground service personnel and equipment.

Before comprehending utility pit systems, it is first necessary to understand how conventional GSE operations are facilitated. Below is a non-exhaustive list of GSE that may be encountered.


Conventionally, aircraft refueling has been facilitated by means of delivery from a self-contained fuel truck or cart. These vehicles contain all of the equipment necessary to carry out pumping operations, but can only hold up to 10,000 gallons of fuel.

Ground Power Units

In addition to fuel, aircraft go through an incredible amount of electricity during a single flight and will require significant recharging in between flights. The current modus operandi involves the delivery of a mobile power unit to the aircraft to supply the energy needed.

Container Loaders

Serving the purpose of loading cargo onto the aircraft, container loaders are electric or gas-powered vehicles capable of supporting thousands of pounds.

Air Start Unit

Although most aircraft may be started using the auxiliary power unit (APU), there may be situations where the plane is not equipped with one, or the device stops working. In any case, an air start unit may be used to provide high-volume air to the engines to help facilitate their start-up.

General Pumps

Aircraft require both the disposal of waste material and the delivery of clean water. Both of these actions require a pump, which is either electrically or gas-powered.


After reviewing the various equipment types found in GSE operations, it becomes clear that the limiting factor is the availability of "hard" resources, such as fuel, electricity, and compressed air. In almost every case, the equipment must be brought close to the aircraft while also requiring their own refueling at some point. The solution to this? Utility pit systems. Pit systems allow for necessary resources to be placed in close proximity to the aircraft and ground service equipment while also reducing the necessity for long hoses and wires. As a result, there is less clutter on the tarmac, faster and more continuous service, and fewer incidents involving a vehicle or aircraft running over lines.

In all pit systems, the connectors are contained in an underground module that remains retracted when not in use. A hatch-pit design features a small, hinged door that contains the connectors on the bottom. Although this configuration takes up less space and is quicker to deploy, it is less ergonomic for ground support staff, who have to bring the lines from ground level to the target. The alternative solution is the pop-up pit system, which may be brought up to any height desired, thereby reducing the strain on personnel. In either case, the hatch of the pit system should be durable and capable of supporting the weight of an aircraft tire.

When you are in the market for premium GSE equipment and tools, look no further than ASAP NSN HUB.

Fixed-wing aircraft facilitate controlled flight by manipulating several moving components called control surfaces. These surfaces, which include the rudder, flaps, elevators, and ailerons, help to guide the plane as it travels through the air with smoothness and safety. While each of these elements plays a critical role in aerodynamics, this blog will focus on the design, operating principle, and various types of ailerons.

The word aileron is French for "little wing," which accurately describes the component's design and function. Shortly after the Wright brothers first took flight, it was realized that while lift could be sufficiently generated using wings, lateral movement and banking would be impossible with only fixed flight surfaces. As a result, a cable system was added to early aircraft, which would initiate those movements by gently warping the wings. Although wing-warping produced favorable results, particularly in the context of coordinated turns, they quickly fell out of favor when moveable ailerons became more advanced.

Nearly all modern ailerons are found on the trailing edge of both wings and are directly connected by the actuation system. When the pilot initiates movement of one aileron, the other will move in an inverse manner. For example, if the left aileron pushes down, the one on the right will move up. The aerodynamics involved in ailerons are relatively straightforward in that a downward movement causes increased lift on that wing, while the upward-facing aileron experiences decreased lift. The result is a banked turn in the direction of the upward-facing aileron.

Most commonly, ailerons are positioned away from the center of the wing, closer to the fuselage. However, their placement is highly variable, and larger planes demand a higher surface area in order to facilitate banking. A significant technological upgrade came from the implementation of multiple ailerons, capable of moving independently from each other, on both wings. Such designs are ubiquitous among large passenger and cargo aircraft. Using an "inboard-outboard" aileron configuration is beneficial in several ways. First, it helps to ensure system redundancy in the rare event of actuation system failure since each element is controlled by a separate hydraulic control module or cable. Also, it helps to prevent incorrect net-roll torque by locking out the outboard ailerons when the aircraft reaches a high enough speed.

While ailerons play a critical role in banking and coordinated turns, they also produce the unwanted side effect of adverse yaw. Adverse yaw occurs when the nose of the aircraft begins to point in the direction opposite of the aileron-facilitated roll. This causes instability and roughness in a coordinated turn and must therefore be counteracted. To compensate for the adverse yaw produced by the ailerons, rudders are used to create an opposite sideways force to level the aircraft.

Like other flight control surfaces, ailerons contain trim tabs to aid pilots in performing continuous movements without fatigue. Additionally, trim tabs work to reduce drag, which saves on fuel efficiency and may dampen the magnitude of adverse yaw. Another, much less common, use of trim tabs is to help control the plane when controls are damaged. Although there is minimal precedent for this in general aviation, there have been several well-documented examples of military aircraft being able to operate with just trim tabs.

When inspecting the ailerons, ensure that they are free of debris and damage. As with all movable surfaces and hinged devices, it is necessary to examine the various rivets for distortion and tightness. If any maintenance is performed, it is crucial for the ailerons to be rebalanced and tested to ensure proper mechanical movement. Finally, it is important to procure replacement parts from a trusted source.

At ASAP NSN Hub, we carry millions of high-quality components for the civil and military aviation industries, including a wide selection of aileron parts. We are an AS9120B, ISO 9001:2015, and FAA AC 00-56B accredited enterprise and the only distributors to maintain a strict NO CHINA Sourcing policy.

Aircraft hydraulic systems allow operators a way of remotely controlling an array of components by transmitting force through a pressurized fluid. Hydraulics can quickly and accurately generate high forces through lightweight pipes of varying sizes, shapes, and lengths. Furthermore, they serve as the primary sources of power in aircraft systems like flight controls, flaps, wheel brakes, and more.

Modern aircraft have many different types of subsystems, some of which are interlinked. One such system is the hydraulic subsystem, which is utilized for actuating most of the mechanical subsystems, including landing gear, flap brakes, weapons systems, and various others. As a result, it becomes apparent that the hydraulic system is an essential part of aircraft functionality.

A hydraulic system consists of a pressurized liquid within a sealed system that is used to transmit energy. Hydraulic systems take engine power and convert it to hydraulic power via a hydraulic pump. This power can then be distributed through tubing that runs across the entirety of the aircraft. Similarly, this hydraulic power can be changed back into mechanical power by way of an actuating cylinder or turbine.

One of the main parts of the hydraulic system is the actuating cylinder which is tasked with changing hydraulic fluid power into mechanical shaft power. Within the actuating cylinder, a rotating piston is regulated by oil under pressure. The oil is in contact with both sides of the piston head but at varying pressures, and high pressure oil can be pumped into either side of the piston head.

Meanwhile, the selector valve dictates which side of the actuating cylinder will receive the high pressure oil The piston rod of the actuating cylinder is connected to the control surface. As the piston moves out, the elevator moves down and vice versa. At the same time, the selector valve directs the high pressure oil to the appropriate side of the piston head, making the piston move in the actuating cylinder.

As the piston moves, the oil on the low pressure side makes its way back to the reservoir. The pressure differential causes the piston to move, and the force generated by this difference in pressure is ample enough to move the necessary loads. It is important to note that cylinders within boats, planes, and other vehicles are specially designed to carry out the aforementioned process with ease.

The reservoir is responsible for a few different things, some of which we will outline. First, it provides air space for the expansion of the oil due to temperature changes. Additionally, it holds a backup supply of oil to account for the thermal contraction of oil, normal leakage, and volume changes due to operational requirements. The reservoir also provides a place to remove air or foam from the liquid as well as a pressure head on the pump.

There are two types of power pumps, those of which are gear pumps and piston pumps. A gear pump moves fluid based on the number of gear teeth and the volume spacing between gear teeth. This pump type is ideal for operations that need pressures up to 1500 PSI. A piston pump, on the other hand, moves fluid by pushing it through the motion of the pistons within the pump.

Aircraft windows are an important element of the fuselage that provide crew members and passengers a view of the outside atmosphere and allow for safety and comfort to be upheld with ease. With the intensive atmospheric conditions present in the altitude range aircraft typically travel at, airplane windows have to be designed with ample integrity and strength. In this blog, we will discuss how airplane windows are designed and the various materials that make them up.

Unlike typical windows that are made from standard glass materials, aircraft cabin window assemblies are constructed from plastics and special polymers. Furthermore, multiple layers of material are overlaid atop of one another to increase the overall strength and reliability of each window. If a cabin window was designed from glass, it would quickly shatter as soon as the extreme pressures set in at higher altitudes. As such, it is not a viable material with its lack of pressure resistance.

As stated before, airplane windows are made from multiple layers of materials, and each of these layers has a specific name and role. Generally, the primary elements of an aircraft window assembly include the passenger window frame, outer windowpane, combined seal, middle window pane, and scratch pane. The outer pane remains flush with the fuselage, and it is often the most robust section that passengers cannot interact with. Meanwhile, the middle window pane serves to equalize pressure, featuring a small breather hole that allows cabin air to escape into the pocket. This is highly beneficial as it forces the outer window pane to take the brunt of the load at a slow pace that avoids losses in integrity. Lastly, the most inner pane is the scratch pane, and it is the thinnest of the assembly as it is simply a non-structural element that prevents passengers from scratching windows.

When traversing wetter climates where fog, rain, or other moisture is present, it is important that visuals are not lost. Often, airplane window exteriors are equipped with an anti-fog system in the form of coatings that maintain clarity. Anti-ice coatings are also extremely important as ice deposits can detract from aerodynamics through the disruption of airflow and generation of drag. While cabin windows are provided the ability to deter loss of visuals, flight deck windshields feature the most robust systems for the means of bolstering a pilot’s abilities to maintain sight out of the aircraft.

For a jet engine to properly function with high performance and reliability, it requires a continuous flow of oil. Oil plays various roles for an engine assembly, serving to cool hot parts, lubricate moving assemblies, and remove the buildup of debris. For the oil system to function with ease, all parts need to function together so that oil can be stored, cooled, directed, and distributed as necessary. With the grand importance of the jet engine oil system, it can be very beneficial to have a general understanding of its design and functionality for proper care and use.

In order for oil to reach various aircraft engine components, it must be transported through various pipes and internal flow passages. When the engine is completely shut off, there is a possibility of a siphoning effect occurring, that of which causes tank draining when the tank is situated above the supply nozzle. To prevent such issues from happening, an anti-siphon system should be installed. Another issue faced by oil systems is unusual output pressure values that come about during cold starts, that of which poses a risk to the supply pump. To prevent damage, a pressure relief valve will be installed.

For a pilot to guarantee the proper functionality and health of the jet engine oil system during flight, a monitoring system is typically used. This system ensures that a pilot can remain aware of oil supply pressure, temperature, and quantity, as well as the amount of debris released by oil sumps. With more advanced systems, pilots may also be able to record and analyze monitored data for maintenance endeavors.

As stated beforehand, one of the main roles of the oil system is to supply oil to various aircraft hardware parts for a means of achieving lubrication. Lubricating oils are especially important for all bearings and gears of the engine assembly, those of which use oil to minimize the amount of friction and wear faced during standard operations. When transporting oil for lubrication, it is important that the pressure within the sumps is always lower than the exterior pressure, ensuring that leaks do not occur. If a leak were to happen, pollution may spread to air bleed components, potentially leading to an engine fire. Because of this hazard, it is paramount that regular inspections are carried out for all aircraft engine components, oil system parts, carbon seals, and other related items.

Lubricating oil is supplied through two or more oil sumps, and each is pressurized and sealed for proper functionality. To prevent poor oil quality and excessive heat, a proper amount of oil should always be supplied. Additionally, different types of oils may vary in their level of maintenance, speed ranges, and other properties, making it important that operators properly choose products that accommodate their needs. If you are in the market for various jet engine oil system hardware parts that you can rely on with ease, there is no better alternative to ASAP NSN Hub.

When an aircraft is parked at a terminal or is otherwise grounded with all engines and power units shut off, power is unable to be generated for various internal systems and electronics. Whether the aircraft is being prepared for its next flight or is simply being inspected for system functionality, there will need to be a source of power provided without utilizing the engines for safety and fuel savings. With an aircraft ground power unit (GPU), electrical power can be provided from an external source to various aircraft parts and systems with ease. As GPUs serve as a common form of ground support equipment that is extremely useful for aviation applications, it can be beneficial to have a better understanding of them.

During standard flight, the air conditioning system, avionics, lights, and all other powered components are supported by the jet engines in operation. During touchdown, the pilot will often maintain power for one engine so that the aircraft has enough thrust to get to the terminal and ample power to continue running necessary systems. While thrust will no longer be needed when at the terminal, power will still be required for aircraft docking, turnovers, and instrumentation tests, thus necessitating the use of external ground support equipment.

While pilots have the option of using the auxiliary power unit (APU) to provide electricity, its operation will result in excessive amounts of noise and the burning of fuel which can be considered more wasteful. As such, the 400 Hz aircraft ground power unit has become a staple of many regulatory bodies and aviation applications. The 400 Hz standard is very important, as it ensures optimal transmission with low losses while minimizing the weight and size of all electrical components and motors present in the aircraft. By using a higher electrical frequency than what is considered the global standard for most systems, aircraft electrical assemblies can be designed to be highly efficient and lightweight.

In general, the aircraft ground power unit is a type of box with a flexible cable that directly plugs into the aircraft. The GPU is typically connected before the engine is shut off, ensuring no hiccup in electrical power is experienced. Once all tests and verifications are complete and the interlocking LED is lit, the operator may turn on the adapter so that the electrical connection is established for power to be provided to the aircraft. Depending on the type of the aircraft and its size, one or more GPUs may be used, and the GPUs may be fixed-to-ground, bridge mounted, or mobile types.

When choosing between different GPU options, one should consider the flexibility and mobility they require, their power source, the space of the particular airport, and other such factors. At ASAP NSN Hub, we are a leading distributor of aircraft parts and ground power unit components that have been sourced from leading global manufacturers that we trust. As you explore our vast set of offerings, take advantage of our RFQ services to request quotes on items for your comparisons with ease. Once you have submitted a form, our team members will quickly review it and respond with a customized solution for your needs, all within 15 minutes or less.

In the realm of aviation, a stall refers to an aerodynamic condition in which lift is lost as a result of the disruption of smooth airflow over wings. As stalling is a very hazardous condition that can lead to an accident, it is important that pilots have ample training on how to recover themselves when it occurs. While understanding the basics of stall recovery is essential, it is also highly useful to be aware of the most common mistakes that pilots make during such procedures.

During a banking turn, it is possible that the lowered wing will face a stall. When this occurs, one may think it best to utilize the ailerons to maintain orientation. While this may be an optimal method during standard flight, increasing the angle-of-attack (AOA) on each wingtip with the ailerons during a stall can potentially cause aileron deflection to surpass the critical AOA. When this occurs, the entire wing will stall as the aircraft begins to roll in the direction of the higher AOA.

Back pressure is another concern during stall recovery, that of which should be gradually added to the elevator during a steep level flight turn. If a significant amount of back pressure is added to the elevator, a secondary stall may occur due to an excessive angle-of-attack. If this happens during a recovery, the nose should be lowered while power is gradually added before attempting the stall recovery again.

In general, the primary method of recovering from a stall is to reduce the angle-of-attack of all affected flight surfaces, though it is important that decreases in altitude are controlled and minimal. Typically, one will want to slowly release back-pressure while increasing energy, and once the aircraft is ready, a climb may be attempted again. During such procedures, a pilot should not lose hundreds or thousands of feet of altitude, and pointing the nose straight down to decrease the aircraft’s AOA is unsafe.

While conducting any recovery, the heading of the aircraft should be governed with the use of rudder pedal controls from within the cockpit. During the recovery, asymmetric thrust will often cause the aircraft to begin turning left, and the pilot can utilize the right rudder pedal to counteract such forces to maintain alignment. It is also important to keep the nose straight forward during the recovery process as well. Alongside management of the rudder pedal, pilots should also ensure that the throttle is used to apply full power in a smooth fashion.

The last major mistake that pilots make during a stall is how they fly the aircraft before, during, and after recovery. Whenever a stall occurs, it is paramount that the pilot maintains coordinated flight. With the use of rudder pedals, ailerons, and other flight control surfaces, pilots should correct undesirable forces, turns, and more. If a pilot remains uncoordinated throughout a stall, they have a chance of entering a spin which is highly dangerous.

With proper stall recovery training and a reliable aircraft, pilots can keep themselves safe during flight operations.
