Ball Bearings
Open bearings dissipate heat more efficiently than shielded and sealed bearings.

Permanently Lubricated Ball Bearings
A solid polymer lubricant surrounds the balls, eliminating the need for additional lubrication. Because it's solid, the lubricant blocks out water and dust, extending the life of the bearing.

Shims for Ball Bearing Housings
Also called tolerance rings, these rings are for use in stamped, molded, or worn housings to form a tight hold on the bearings. They work like a spring, creating tension between the bearing and the housing to hold the bearing in place. They also reduce vibration and compensate for some thermal expansion between the housing and the bearing and eliminate the need for keys, pins, and adhesives. They're made of stainless steel for corrosion resistance.
