About Ball and Roller Bearings

Permanently Lubricated Stainless Steel Ball Bearings

A solid polymer lubricant surrounds the balls, eliminating the need for additional lubrication. The solid lubricant blocks out water and dust, extending the life of the bearing.
Sealed bearings have even better resistance to dust and contaminants than open bearings.

Ultra-Thin Ball Bearings


These bearings have twice as many contact points as angular-contact ball bearings. Fit onto large-diameter hollow shafts to run air and hydraulic lines, electrical wiring, and other components through moving parts in assemblies such as index and rotary tables, packaging equipment, and robotics.
Open bearings dissipate heat more efficiently than shielded bearings.
Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open 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. An arrow on the lip indicates the rotational direction that locks the bearings.
Triple-row bearings support radial loads.
Bearings with 301 stainless steel springs handle higher temperatures than bearings with acetal springs.
