This single row cylindrical roller bearing carries two ribs on the outer ring and a smooth (rib-free) inner ring, allowing axial displacement between the rings and making it suitable as a non-locating bearing on a shaft. Bore diameter is 80.0 mm, outside diameter 170.0 mm, width 58.0 mm, net mass 5.746 kg. The E design provides an optimized internal geometry for increased load carrying capacity, and the bearing is fitted with a glass-fiber reinforced polyamide cage (TVP2). Limiting speed is 5500 1/min, reference speed 3450 1/min. Radial internal clearance is C3, wider than standard, compensating for tighter fits and thermal expansion during operation. Running accuracy is manufactured to P6 tolerance class, giving tighter dimensional and rotational accuracy than standard P0 bearings. The separable inner ring and outer ring with roller and cage assembly simplify mounting and dismounting, while the axial freedom from the non-locating design accommodates shaft length changes without inducing axial preload.
