This single row cylindrical roller bearing is built as a locating bearing, with two ribs on the outer ring, one rib on the inner ring, and a loose rib washer, corresponding to type NUP. Bore diameter is 45.0 mm, outside diameter 100.0 mm, width 25.0 mm, and net mass 0.93 kg. The E design provides an optimized internal geometry for increased load carrying capacity, and the bearing runs with a polyamide cage (TVP2). Limiting speed is 9800 1/min, with a reference speed of 6400 1/min. The rib arrangement allows the bearing to carry radial loads while locating the shaft axially in one direction, as the inner and outer ring can be displaced relative to each other only within the limits set by the rib configuration. Radial internal clearance is CN (Group N), suitable for standard fit and operating conditions without additional clearance adjustment. The polyamide cage design supports smooth roller guidance at the specified speed ratings, and the bearing is intended for grease or oil lubrication as appropriate to the application's speed and load requirements.
