This cylindrical roller bearing carries a stud with fixing thread and a mounting aid, allowing direct bolt-in installation without a separate housing. The outer ring is particularly thick-walled with a central rib that provides axial guidance together with the full complement of cylindrical rollers arranged in a double row. Outside diameter is 47.0 mm, width 66.0 mm, and net mass 0.377 kg. There is no eccentric collar on this version. Sealing is provided on both sides by protected lip seals (2RS), keeping contaminants out of the raceway and retaining grease inside the bearing. The full complement roller set gives increased load capacity for its size, while the rib-guided outer ring keeps axial position stable under load. The design is suitable for direct mounting on a track or guide surface where the outer ring itself acts as the rolling contact element.
