Stainless Steel Ball Bearings
Bearings are 440C stainless steel for good corrosion resistance.
Open bearings dissipate heat more efficiently than shielded and sealed bearings.
Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings.
Bearings with extended inner ring provide additional shaft support.

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.

High-Temperature Ball Bearings
Made with either PEEK or graphite, these ball bearings work in applications that are too hot for most other ball bearings.
PEEK bearings handle temperatures almost twice as high as that of our other plastic ball bearings. They also have good chemical resistance and excellent corrosion resistance.
