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

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

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

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

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

Thrust washers are used as a bearing surface for rotary applications.

Precision locknuts are used to secure bearings, gears, and other power transmission products to shafts and spindles
