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

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

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

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.

Needle-Roller Thrust Bearings

Thinner rollers allow these bearings to fit in tighter spaces than tapered-roller thrust bearings.

Washers for Needle-Roller
Thrust Bearings

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

Combination
Ball/Needle-Roller Bearings

Combination Ball/Needle-Roller Bearings

A built-in thrust ball bearing reduces wear from adjacent shaft components, while the needle-roller bearing supports radial loads.

Mounted Roller Bearings
with Two-Bolt Flange

These roller bearings handle extremely high speeds for their small size.

Mounted Roller Bearings

default

Roller bearings have a thinner profile and larger contact area than ball bearings, making them stronger and more space-efficient than ball bearings.
