Stainless deep groove ball bearings have a very wide range of applications, making them the most common bearing type in electric motors, for example. A deep groove ball bearing has a simple structure, is suitable for high rotational speeds, and requires minimal maintenance. These features, along with their economical price, make deep groove ball bearings the most widely used rolling bearings.

Deep groove ball bearings are available in sealed (greased for life) or open configurations.
