This single-row cylindrical roller bearing, type NJ, has a bore of 45.0 mm, outside diameter of 85.0 mm, and width of 23.0 mm, with a net mass of 0.53 kg. The outer ring carries two ribs and the inner ring one rib, giving it a semi-locating function that allows axial displacement in one direction while guiding the shaft in the other. It runs with a TVP2 polymer cage and C3 radial internal clearance, and the E design provides an increased load rating within the same envelope dimensions. Limiting speed is 11800 1/min, with a reference speed of 5800 1/min. The semi-locating design suits applications where axial free movement must be combined with radial guidance on the same bearing position, compensating for thermal expansion of the shaft. The C3 clearance offsets the temperature rise from interference fits and normal operating conditions, while the TVP2 cage supports smooth roller guidance and grease or oil lubrication at the stated speed ratings.
