HeavY-duty needle roller bearings

MR series heavy duty needle roller bearings, which can be equipped with seals and inner rings, have an inner ring which is removable from the outer. In this configuration the rollers can ride directly on the shaft as long as the shaft has the proper Rockwell hardness and tolerance. 

Heavy Duty Caged Needle Rollers. Carter CMR heavy duty needle roller bearings are well suited to applications where shaft misalignment and higher speeds exceed the capabilities of full complement needle roller bearings. Our CMR bearings are comprised of an outer housing, a precision tubular cage and a set of precision ground needle rollers.
