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.Deep Groove Deep groove, or single row radial, ball bearings are the most widely used bearings. They utilize an uninterrupted raceway that makes them optimal for radial loads.This design permits precision tolerance, even at high-speed operation.Deep Groove Ball Bearings. Also referred to as radial ball bearings, these bearings are the most popular and widely used in industrial machinery applications because of their versatility. Deep groove ball bearings carry loads from rotating parts to the shaft and/or housing with minimal friction.


Radial Ball bearings can support moderate radial loads and moderate axial loads (parallel to the shaft). They can operate at high speeds (400,000 RPMs and higher). Ball bearings with shields or seals for protection can be lubricated to last for the operating life. Sometimes ball bearings are also called “deep groove ball bearings.” AST Bearings is the leading ball bearing supplier.
