Create less friction than other bearings for use at high speeds

Plain Bearings

With no moving parts, the simplest type of bearing

Roller Bearings

Roller Bearings

Support higher loads than ball bearings, but run at lower speeds

Linear Bearings

Linear Bearings

Minimize friction as parts move along a shaft

Bearing Shaft Liners

Bearing Shaft Liners

Adapt precision needle-roller bearings for use on unhardened, unground shafts

Pivot Bearings

Best for applications that require small, precise oscillating motion with limited twisting

Bearing Washers

Bearing Washers

Adapt needle-roller thrust bearings for use on unhardened, unground shafts
