Caged needle bearings possess an outer ring made from through hardened bearing steel. The cage guides, the needles and retains them in the outer ring. The bearings may be used without an inner ring if the shaft journal serving as a raceway is of sufficient hardness and has the correct surface finish. To ensure that the full load capacity of these bearings is achieved, a hardness of 58-64 HRC is required. Cam followers are designed to rotate directly on cams, flat surfaces or guidex. In order to meet the unusual conditions of use – significant loads accompanied by substantial and repeated shocks.
