About Ball and Roller Bearings

Ball Bearings

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.

Sealed bearings block out dust and other contaminants better than open and shielded bearings, but retain the most heat.

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.

Angular-Contact Thrust Ball Bearings

Open

Install these bearings for use with combined radial and thrust loads. They are often used in spindle applications and can be combined with cylindrical roller bearings to better handle radial loads.

Single-row bearings handle thrust loads on one side. For applications with thrust loads on both sides, mount them in pairs.

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