This single row cylindrical roller bearing has a bore of 50.0 mm, outside diameter of 90.0 mm, and width of 23.0 mm, with a net mass of 0.652 kg. The outer ring carries two ribs and the inner ring one rib, giving a semi-locating design (type NJ) that allows axial displacement in one direction while providing guidance in the other. It is fitted with an M1 cage and features the E design for increased load capacity. Limiting speed is 14500 1/min, reference speed 5300 1/min. Radial internal clearance is C3 (Group 3), which compensates for temperature-related fit tightening and shaft deflection during operation. The semi-locating arrangement allows the bearing to accommodate axial movement of the shaft in one direction, making it suitable for arrangements where thermal expansion must be absorbed at one bearing position while radial and partial axial guidance is maintained. As an open bearing without integrated seals, it requires external sealing and a separate lubrication supply, either grease or oil, appropriate to the application's speed and temperature conditions.
