This single-row cylindrical roller bearing has a bore of 35.0 mm, an outside diameter of 72.0 mm and a width of 23.0 mm, with a net mass of 0.428 kg. The outer ring carries two ribs while the inner ring is smooth (no ribs), forming a type NU non-locating design that allows axial displacement between inner and outer ring. It is fitted with an M1 cage, built in the E design for increased load carrying capacity, and runs with C3 (Group 3) radial internal clearance. Limiting speed is 18300 1/min, reference speed 7200 1/min, and running accuracy corresponds to class P6. The non-locating layout compensates for axial shaft expansion, making this bearing suitable for the free-side position in a shaft support arrangement, while the smooth inner ring allows the inner ring to move axially relative to the roller and cage assembly. The C3 clearance accommodates thermal expansion under operating temperature rise, and the P6 accuracy class supports applications requiring tighter running tolerances than standard class. The M1 cage guides the rollers at higher speeds within the stated limiting and reference speed values.
