Power Transmission

Roller Bearings

Roller Bearings

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

Thrust Bearings

Thrust Bearings

Support loads parallel to the shaft with plain, ball, or roller bearings

Thrust Roller Bearing Washers

Thrust Roller Bearing Washers

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

Ball Screw/Splines

Ball Screw/Splines

Transmit rotary power, move loads along the shaft, or do both at once

Spline Bearings

Spline Bearings

Add to splines to transfer rotary power or move loads along the shaft
