Control and airframe aircraft bearings are designed to meet the rigorous demands of aircraft control and aerospace applications

Ball bearings are used to provide smooth, low friction motion in rotary applications. Ball bearings types include radial ball bearings (deep groove and angular contact) and thrust ball bearings

Angular contact bearings are designed so that a contact angle between the races and the balls is formed when the bearing is in use

Roller bearings are used in rotary applications to replace sliding movement with low friction, rolling motion. The principal types of roller bearings are cylindrical, spherical, and tapered

Tapered roller bearings consist of an inner ring (cone), an outer ring (cup), a cage and rollers, which are profiled to distribute the load evenly across the roller

Radial or deep groove bearings can handle radial and axial loads to varying degrees, but are typically used when the primary load is in the radial direction

Cylindrical roller bearings have high radial-load capacity and moderate thrust loads. They contain rollers which are cylindrically-shaped, but crowned or end-relieved to reduce stress concentrations

Needle roller bearings are designed for radial load applications where a low profile is desired

Spherical roller bearings are self-aligning, double row, combination radial and thrust bearings. They use a spherical or crowned roller as the rolling element

Thrust bearings are designed for pure thrust loads, and can handle little or no radial load. The rolling element in a thrust bearing can be a ball, needle or roller

Ceramic hybrid bearings, the most common type of ceramic bearing, are constructed of steel inner and outer rings with ceramic (typically Si3N4) balls in place of steel.  Common types of ceramic bearings are angular contact and conrad

Hanger bearings are used as rotational bearings for drive and screw conveyor shafts that are enclosed with a housing or trough

Air bearings use a thin film of pressurized air to support a load. They do not generate friction

Rod end bearings contain a bearing that can accommodate a shaft or rod with varying misalignment. They attach to a static rod via a threaded shaft

Pivot bearings are used for pivotal, angular, or oscillating applications
