Aircraft Bearing Parts Listing - Page 7

Bearings aide the linear or rotational movement within a machine. They are small devices that help to reduce friction in a machine. Bearings have smaller surface area than two larger moving parts, therefore the level of friction is reduced.

Bearings come in all different shapes and sizes. A few types of bearings are ball bearings, baffle bearings, screw bearings, roller bearings, needle bearings, and actuator bearings.

We at NSN Purchasing, owned and operated by ASAP Semiconductor, supply aviation parts worldwide. A few of the manufacturers that provide premium bearings are Aurora, McGill, NTN Bearing Corp, Barden, Timken, RBC, SKF, and Precision Division.

Bearings in Aerospace

Bearings are found in aircraft, UAVSs, and spacecraft. The FAA regulates every aspect of an aircraft; therefore, bearings must be manufactured to a high standard according to rules and regulations. The environment in which an aircraft functions requires aircraft components to be durable and robust. Bearings must be able to withstand changes in temperature and pressure in particular.

• Fixed-wing Aircraft Bearings

In fixed-wing aircraft bearing bearings are used in both the main airframe and the interior mechanisms of the plane. For example, bearings are used in the mechanism of trim tabs. Bearings are also used in the doors of the aircraft.

• Rotary-Wing

Bearings can be found in the tail rotor, main rotor, landing gear, and the engine of a rotary-wing aircraft. The motor mechanism of a rotary wing aircraft is particularly dependent on bearings such as the main rotor swashplate slider bearing.

Bearing in Automotives

Bearings are usually found in any mechanism that produces movement. The areas in which bearings are used include the wheels, clutch, landing gearbox, and suspension system. Ball bearings are often used in automobiles.

Bearings in Marine Craft

The top consideration when using bearings within marine craft is the level of salt that the bearings will be exposed to. Bearings are featured heavily in various marine craft such as passenger vessels, cargo ships, fishing boats, and tankers. Lead bronze, bi-metal, and tri-metal materials are typically used to make marine bearings. These materials are less susceptible to corrosion therefore require less maintenance than traditional bearings. Examples of marine bearings include thrust pad bearings, pedestal bearings, top bearings.
