Deep Groove Ball Bearing 608-2RS Deep groove ball bearings are versatile, self-retaining bearings with solid outer rings, inner rings and ball and cage assemblies. These bearings with their simple design, high resistance and low-maintenance, are available in single-row and double-row designs, as well as sealed and unsealed. Due to the manufacturing processes used, open bearings can have turned recesses in the outer ring for seals or shields. Thanks to their low frictional torque, deep groove ball bearings can be used for high speeds. MOQ: 1000 PC
