This single row cylindrical roller bearing carries two ribs on the outer ring and one rib on the inner ring, giving it a semi-locating function that allows axial displacement in one direction while guiding the shaft in the other. Bore diameter is 90.0 mm, outside diameter 160.0 mm, and width 30.0 mm, with a net mass of 2.65 kg. Limiting speed reaches 7800 1/min, reference speed 3900 1/min. The bearing is fitted with an M1 cage and built to E design for increased load capacity. Radial internal clearance is set to C3 (Group 3), which compensates for thermal expansion under higher operating temperatures or interference fits. The semi-locating arrangement makes this bearing suitable for shaft positions where one bearing must absorb axial forces while a floating bearing at the opposite end takes up thermal length changes. As an open design without an integrated seal, lubrication and sealing must be provided externally, and mounting should account for the roller-rib guidance when aligning the shaft.
