This 6006-2RS 30x55x13-millimeter sealed ball bearing has deep groove for high speeds and supporting both radial and axial load. It has rubber seals on both sides of the bearing to keep lubricant in and contaminants out, and comes pre-lubricated from the factory so that no additional lubrication is required. This bearing is for use in applications that involve combined radial and axial loads, and a need for high running accuracy at high rotational speeds. These applications include clutches, drives, gearboxes, compressors, pumps, turbines and others. Part Number: 6006-2RSR
