This cylindrical roller bearing carries radial loads in a single row configuration, with two ribs on the outer ring and one rib on the inner ring, forming a semi-locating bearing that allows axial displacement in one direction while providing guidance in the other. Bore diameter is 80.0 mm, outside diameter 140.0 mm, width 33.0 mm, and net mass 2.409 kg. Limiting speed reaches 9000 1/min, with a reference speed of 3400 1/min. The design follows the E series with an M1 machined cage. Radial internal clearance is set to C3 (Group 3), suitable for applications with elevated operating temperatures or interference fits requiring additional internal play. The semi-locating design permits axial movement of the shaft in one direction, making it suitable as a floating bearing position where thermal expansion or misalignment along the shaft axis needs to be accommodated, while the ribs on both rings maintain radial guidance and roller alignment under load.
