W 6209-2Z Deep groove ball bearing

Stainless deep groove ball bearings have a very wide range of applications and are the most common bearing type, for example, in electric motors. The deep groove ball bearing has a simple structure, is suitable for high rotational speeds, and requires minimal maintenance. These features, combined with a low price, make deep groove ball bearings the most widely used rolling bearing. Deep groove ball bearings are available in sealed (permanently lubricated) or open designs.
