This cylindrical roller bearing is a single-row locating bearing with a two-rib outer ring and a one-rib inner ring plus a separate rib washer, matching the NUP design layout. Bore diameter is 30.0 mm, outside diameter 72.0 mm, width 19.0 mm, and net mass is 0.351 kg. The E design provides increased load rating within the same envelope. Limiting speed is rated at 14200 1/min, with a reference speed of 8900 1/min, and the cage is a glass-fibre reinforced polyamide type TVP2. The rib arrangement allows the bearing to function as an axial locating point on the shaft while carrying radial loads through the cylindrical roller set. Radial internal clearance falls in group CN, suited for standard fit and temperature conditions without added preload. The polymer cage reduces friction and mass compared with a solid cage, supporting the stated speed ratings, and the open design requires external sealing and lubrication provisions at the housing.
