This single-row cylindrical roller bearing supports radial loads at a bore diameter of 25.0 mm, outside diameter of 52.0 mm and width of 15.0 mm, with a net mass of 0.129 kg. The outer ring carries two ribs and the inner ring one rib with an internal rib washer, giving the NUP design its axial locating function on one side while the other side allows free axial displacement. Limiting speed is rated at 19800 1/min and reference speed at 11600 1/min, with radial internal clearance in group CN. The polyamide cage (TVP2) and E design reduce running friction and support the rated speed values, making the bearing suitable as a locating bearing where axial fixing in one direction combined with free thermal expansion is required. Standard CN clearance suits general-purpose mounting without preload, and the open design requires external sealing and lubrication provision at the point of installation.
