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.

Precision Stainless Steel Ball Bearings

Open

Shielded

Made to tight tolerances, these 440C stainless steel bearings combine speed and accuracy with corrosion resistance.

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.
