Deep Groove Ball Bearings

Deep groove ball bearings are the most common type of rolling bearings. Deep groove ball bearings are mainly used for pure radial loads, but also can stand small radial load. Because of their low torque, they are highly suitable for applications where high speeds and low power lose are require. Deep groove ball bearing structure is simple, and manufacturing costs is low, widely used in transmission, instrumentation, motors, household electrical, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery and engineering machinery.

For deep groove ball bearings, pressed cages are usually used. For large size bearings and high-speed applications, machined brass cages are used.

Size range: 280 mm to 850 mm I.D
