About Ball and Roller Bearings

Needle-Roller Bearings

Also known as drawn-cup roller bearings, these are our thinnest roller bearings. The outer ring is drawn out to form a lip that holds the bearing together.

Precision Needle-Roller Bearings

These bearings have higher radial load capacity, speed, and accuracy than standard needle-roller bearings.

Shaft Liners for Precision
Needle-Roller Bearings

Adapt high-precision needle-roller bearings to use on unhardened, unground shafts.

One-Way Locking
Needle-Roller Bearing Clutches

The needles in these bearings roll freely in one direction, but lock to transmit torque when the rotation of the shaft is reversed. Also known as drawn-cup roller clutches.
