This single row cylindrical roller bearing carries two ribs on the outer ring and a smooth (rib-free) inner ring, which makes it a non-locating bearing allowing axial displacement between the rings. Bore diameter is 45.0 mm, outside diameter 85.0 mm, width 23.0 mm, mass 0.516 kg. The polyamide cage is designated TVP2, radial internal clearance falls in group CN, running accuracy is in class P6, and the E design provides increased load carrying capacity. Limiting speed reaches 11800 1/min, with a reference speed of 5800 1/min. The smooth inner ring lets the shaft ring shift axially through the roller set, so this bearing takes up thermal expansion or shaft deflection without generating axial preload, while the two ribs on the outer ring keep radial guidance stable. Standard CN clearance and P6 accuracy suit applications requiring normal running precision under radial load, with the free ring side to be lubricated and positioned so axial displacement is not obstructed.
