This needle roller bearing carries radial loads through a particularly thick-walled outer ring, supported by a needle roller and cage assembly running on an inner ring. Bore diameter is 12.0 mm, outside diameter 32.0 mm, and net mass 55.7 g. The design is open, without sealing, and the outer ring has no axial guidance. Inner ring, outer ring and the needle roller and cage assembly can be mounted separately. The thick-walled outer ring gives the bearing high radial rigidity, making it suitable for direct rolling contact applications where the outer surface acts as the running track. Since sealing is absent, the mounting location must provide external protection from contamination and ensure a separate lubrication source, as no integrated grease retention is present. Separate mountability of the inner ring, outer ring and needle roller and cage assembly allows flexible axial positioning during installation.
