Deep groove ball bearings are available in single row and double row designs. Single row deep groove ball bearings are self-retaining units, which are part of the group of radial ball bearings. The solid outer and inner rings have deep raceway grooves, with shoulders which are not generally interrupted by filling slots. Solid cages made from polyamide PA66 or brass, and sheet metal cages made from steel or brass, are used as standard cages. The bearings are open or sealed. Due to the manufacturing processes used, open bearings, which are also available as sealed versions, can have turned recesses in the outer and inner ring for sealing washers or sealing shields.
Single row deep groove ball bearings are particularly versatile, robust in operation, easy to maintain and very economical. Due to their significant advantages, they are the most widely used bearings worldwide. As a result, Schaeffler also manufactures these bearings in a large number of sizes and designs.
