Stainless Steel Ball Bearings
Bearings are 440C stainless steel for good corrosion resistance.
Open bearings dissipate heat more efficiently than shielded and sealed 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.

Plastic Ball Bearings
These acetal bearings have good all-around corrosion and chemical resistance.
316 stainless steel balls have excellent corrosion resistance.
Glass balls have even more corrosion resistance than stainless steel balls.
