This cylindrical roller bearing carries an inner ring with a smooth raceway (no ribs) and an outer ring with two ribs, forming a single-row non-locating design of type NU. The bore is 45.0 mm, outside diameter 100.0 mm, width 36.0 mm, and net mass 1.44 kg. It runs with radial internal clearance C3 (Group 3), an M1A cage, and running accuracy to P6. Limiting speed is 12800 1/min, reference speed 5200 1/min. Because the inner ring has no ribs, the bearing allows axial displacement between inner and outer ring, making it suitable as a non-locating bearing where the shaft needs to move axially relative to the housing. The C3 clearance compensates for thermal expansion during operation, while the P6 accuracy class supports precise radial guidance. The M1A cage design is suited to the speed range indicated by the stated limiting and reference speed values.
