This cylindrical roller bearing is a single-row locating bearing with two ribs on the outer ring and one rib on the inner ring, fitted with a loose rib washer, design NUP. Bore diameter is 75.0 mm, outside diameter 160.0 mm, width 37.0 mm, and net mass 3.83 kg. The cage is a machined brass cage, designation M1, and the internal design follows the E series for increased roller complement. Limiting speed is rated at 7600 1/min, with a reference speed of 4150 1/min. The two-rib outer ring combined with the single rib on the inner ring and the loose washer allows the bearing to carry radial loads while providing axial location in one direction, with the inner ring free to displace axially relative to the outer ring on the non-locating side. Radial internal clearance C3 accommodates thermal expansion and shaft deflection under load, while the M1 cage design supports stable roller guidance at the stated speed ratings. The construction is suited for applications requiring a fixed bearing position on the shaft with tolerance for thermal growth.
