This needle roller bearing serves as a yoke type track roller, guiding a component along an outer race without axial constraint of that ring. It combines a particularly thick-walled outer ring with a needle roller and cage assembly and an inner ring, bore diameter 20.0 mm, outside diameter 47.0 mm, mass 0.158 kg. The inner ring, outer ring and needle roller and cage assembly can be mounted separately, which simplifies fitting and dismounting during assembly work. The design is open, without sealing, so the mounting location must provide its own protection against contamination and its own lubrication supply. As the outer ring carries no axial guidance, this bearing is suited to applications where radial load transfer along a track is required while axial positioning is handled by the surrounding construction.
