Bearing Depot & Supply stocks a full line of rolling-element stainless steel ball bearings in a wide variety of types, series, and sizes. Bearing Depot stocks both metric and inch dimension ball bearings. The balls are either in single or double rows - these bearings allow for reduced sound, friction and problems with the machines down the line. The lifespan of our industrial bearings are long with many applications as long as they are properly installed and measured beforehand.
