This needle roller bearing (NA22/8-2RSR) is a single row design with a particularly thick-walled outer ring, a needle roller and cage assembly, and a separately mountable inner ring. Bore diameter is 8.0 mm, outside diameter 24.0 mm, and net mass 32.0 g. The outer ring has no axial guidance, and sealing is provided on both sides by lip seals (2RSR) acting radially against the inner ring. The thick-walled outer ring gives this bearing high radial load capacity relative to its size, while the double-sided lip seal keeps out contaminants and retains lubricant within the needle roller and cage assembly. Since the inner ring can be mounted separately, fitting and dismounting on the shaft is straightforward without disturbing the outer ring and roller set. The absence of axial guidance on the outer ring means axial positioning must be provided by the surrounding construction.
