This needle roller bearing is a single row design with a particularly thick-walled outer ring, a needle roller and cage assembly, and a separate inner ring that can be mounted independently. Bore diameter is 10.0 mm, outside diameter is 30.0 mm, and net mass is 61.0 g. The outer ring has no axial guidance. Sealing is provided by lip seals acting radially on both sides, marked as 2RSR. The lack of axial guidance on the outer ring allows the bearing to accommodate axial displacement between outer and inner ring, which is relevant when aligning the assembly during mounting. The double-sided lip seal design keeps contaminants out and retains lubricant within the bearing, supporting operation without frequent relubrication. The separately mountable inner ring simplifies fitting and replacement without disturbing the outer ring and needle roller and cage assembly.
