Deep groove ball bearings have a very wide range of applications and are the most common bearing type in electric motors, for example. A deep groove ball bearing features a simple design, is suitable for high rotational speeds, and requires minimal maintenance. These characteristics, along with an affordable price, make deep groove ball bearings the most widely used rolling bearing. Deep groove ball bearings are available in sealed (greased for life) or open structures. They are also available in stainless steel (W prefix).
