Description:

Deep groove ball bearing are the most commom type of rolling bearing and are availabel in both single row and double row desings . There application is very wind. The raceway groove on both inner and outer rings have circular arcs of slightly larger radius than that of the balls. In addition, radial  loads , axial loads can be imposed in either direction. 

Because of their low torque, they are highly suitable for applications where high 

speeds and low power loss are required.
