7040B NSK Ball Bearing

NSK Ball  Bearing

Single-row deep groove ball bearings are the most common type of rolling bearings. Their range of application is very wide. The raceway grooves in both the inner and outer rings have circular arcs of slightly larger radius than that of the balls. In addition to 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.
