This single row cylindrical roller bearing is built in the NU design, with two ribs on the outer ring and a smooth (rib-free) inner ring, allowing the inner ring to shift axially relative to the outer ring. Bore diameter is 110.0 mm, outside diameter 170.0 mm, width 28.0 mm, net mass 2.258 kg. Limiting speed is 7700.0 1/min, reference speed 3850.0 1/min. The bearing is fitted with an M1 cage and radial internal clearance C3. Because of its NU configuration, the bearing acts as a non-locating bearing, compensating for axial displacement of the shaft without transmitting axial load. The C3 clearance offsets thermal expansion during operation, while the M1 cage supports stable roller guidance at the given speed range. Running accuracy corresponds to the P6 tolerance class, suitable for applications requiring improved rotational precision compared to standard tolerance bearings.
