Deep Groove Radial Ball Bearings

The purpose of a radial bearing, also known as a deep groove bearing, is to reduce rotational friction and support loads. This is achieved by using two races to hold the balls and to spread the load through the balls. As the bearing race rotates it causes the balls to rotate. The ball provides for substantially less rolling resistance and coefficient of friction than if two flat surfaces were rotating. The Boca Bearing Company has been an industry leader at miniature radial dep groove bearings since 1987.

Single-row, deep groove radial ball bearings are the most common bearing type, having a wide range of applications. Radial deep groove bearings are made with very high levels of precision and used in applications where rotational performance and low torque is necessary, but load is a secondary issue. Miniature, Deep-groove bearings however do have higher load ratings for their size than shallow-groove ball bearings, but are also less tolerant of misalignment.
