This single row cylindrical roller bearing (NU215-E-XL-M1-C3) has a bore of 75.0 mm, outside diameter of 130.0 mm, and width of 25.0 mm, with a net mass of 1.4 kg. The outer ring carries two ribs while the inner ring is smooth, giving the NU design its non-locating function that allows free axial displacement between inner and outer ring. The bearing is fitted with an M1 cage and features the E design for increased roller complement and load capacity. Radial internal clearance corresponds to C3 (Group 3), and running accuracy is to P6. Limiting speed is 9800 1/min, with a reference speed of 4400 1/min. The non-locating NU configuration makes this bearing suitable for shaft arrangements where axial compensation is required on one bearing position, while radial loads are carried without restriction of axial movement. The C3 internal clearance compensates for temperature-related expansion and interference fit effects, and the P6 accuracy class supports applications requiring tighter running tolerances than standard class. The E design increases the number of rollers relative to the standard NU215, raising radial load capacity within the same envelope dimensions. As a separable bearing, the inner ring can be mounted independently of the outer ring, simplifying assembly and dismounting on the shaft.
