Catalogue of Aircraft Bearing

Bearings help support and guide the rotating or sliding element of a machine, and aircraft bearings is crucial in aerospace industries. There are numerous types of bearings that each help to reduce friction within a machine. Instead of two stationary materials sliding past one another, a bearing streamlines the movement as the surface area of moving parts is reduced, thereby reducing friction and increase efficiency. The efficiency of the machine is increased as the bearings mitigate the amount of power the moving element uses.

Aircraft Bearings come in all different shapes and sizes. Ball bearings, roller bearings, ball thrust bearings, mounted bearings, slide bearing, and jewel bearings are all different categories.

Many different industries use bearings; for example, ball bearings are used in the wheels of inline skates. There are industries that use bearings, and different types of bearings, in most of their machines. These industries are: the aerospace, automotive, and marine industries.

We, at ASAP Axis, owned and operated by ASAP Semiconductor, supply aviation bearing parts from top manufacturers worldwide. A few of the manufacturers that provide high-quality bearings are SKF, NTN Bearing Corp, RBC, and Timken.

Bearings in Aerospace:
If you were to dismantle an aircraft or an unmanned aerial vehicle, you would find multiple aircraft bearings. The bearings used in an aircraft would most likely differ from those found in the UAV. This is because the material of the bearing is carefully considered in relation to the conditions in which it is working. The amount of thrust that an aircraft produces is greater than the amount of thrust a UAV produces. As a consequence, the bearing in an aircraft must be able to withstand more friction. To be deemed airworthy by the FAA, using the correct type of bearing for the equipment is important. If an ill-suited bearing is used in an aircraft, the overall standard of the aircraft could be compromised.

Fixed Wing Aircraft Bearings:
Bearings can be found in aircraft landing gear. Upper and lower bearings are located in the main landing gear structure. The bearings are designed to absorb shock as the plane touches the runway during landing. Bearings are also used to manipulate control surface such   as ailerons.

Rotary Wing Aircraft Bearings:
Motor rotor bearing are specific to rotary wing aircraft. Tail rotor bearings, main rotor swashplate slider bearings and main rotor pitch link bearings are all examples.

Bearings in Automotives:
Similar to aircraft, bearings are used in the moving parts of an automotive: water pumps, transmissions, and wheels. A closer inspection of the inside of a car will show bearings being used in the gearbox, wheels, suspension and clutch.

Bearing in Marine Craft:
Salt is the important element to note with the use of bearings in marine craft. Bearings such as thrust pad bearings, main bearings, and pedestal bearings must have some level of resistance to corrosion. Bronze bearings, tri metal bearings, and bi-metal bearings are popular choices of marine craft bearing material. Bearings can be found on passenger vessels, container vessels and battleship amongst many other marine craft.
