This single row cylindrical roller bearing carries a machined cage (M1) and reinforced internal design (E), giving a bore of 80.0 mm, outside diameter of 140.0 mm and width of 26.0 mm at a net mass of 1.76 kg. The outer ring has two ribs and the inner ring has one rib with an internal rib washer, forming a locating bearing configuration of type NUP. Limiting speed is 9000 1/min, reference speed 4200 1/min, with radial internal clearance in group CN. The NUP design allows the bearing to take up axial loads in one direction in addition to radial loads, while the separable ring construction simplifies mounting and dismounting on the shaft. Standard CN clearance suits general-purpose fits without preload, and the machined M1 cage supports stable roller guidance at the stated speed ratings. As a locating bearing, it fixes the shaft position axially on one side, with the non-located side left free to accommodate thermal expansion elsewhere in the arrangement.
