This single row cylindrical roller bearing carries a full complement roller set, giving it a higher radial load capacity than caged designs of the same envelope. Bore diameter is 20.0 mm, outside diameter 47.0 mm, width 18.0 mm, and net mass is 153.52 g. The outer ring has 1 rib and the inner ring has 2 ribs, forming a semi-locating arrangement, design A. Limiting speed is 12000 1/min, reference speed 6500 1/min, with radial internal clearance in group CN. The semi-locating configuration allows axial displacement in one direction while guiding the shaft in the other, which is useful where thermal expansion or shaft misalignment needs to be accommodated without adding a separate free bearing. The full complement roller set increases contact area for radial loads but requires clean operating conditions and adequate lubrication, since there is no cage to control roller spacing. Standard CN clearance suits general mounting conditions without preload, and the open design allows the use of oil or grease lubrication depending on the operating speed and application requirements.
