Washers are disks of metal or non-metallic material placed beneath a nut, an axle bearing, or a joint, to relieve friction, prevent leakage, isolate, prevent loosening, or distribute pressure

Spring washers are disks of metal that are formed in an irregular shape so that when the washer is loaded it deflects, acts like a spring, and provides a preload between two surfaces

Preload springs, spacers and washers are used to provide end-play take up or a constant preload for bearings, gears and other mechanical components and assemblies

Wave washers or wave springs are wavy metal washers designed to provide a compensating spring force and sustain a load or absorb shock

Thrust bearings are designed for pure thrust loads, and can handle little or no radial load.

Bearing housings and bearing flanges hold an insert bearing in position, support the load transferred from the bearing shaft through the bearing, and are used to mount the bearing to a surface

Ball bearings are used to provide smooth, low friction motion in rotary applications.
