About Ball and Roller Bearings

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.

Tapered-Roller Thrust Bearings

Thick, tapered rollers stand up to extremely high thrust loads.

Tapered-Roller Bearings

Found anywhere from machine tool spindles to conveyor rollers, these bearings have a two-piece design that allows for adjustment.

Face-Mount Crossed-Roller Bearings

Mounting holes on the inner and outer rings allow for fastening onto hollow joints and shafts.

Crossed-Roller Bearings

With a considerably larger ID than our Face-Mount Crossed-Roller Bearings, use these to run hydraulic lines, electrical wiring, and other components through the inside of the bearing.

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.

Spherical-Roller Bearings

Two rows of rollers give these bearings load capacities over five times higher than comparably sized tapered-roller bearings.

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.

Mounted Roller Bearings

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