This cylindrical roller bearing is a single-row locating bearing with a bore of 55.0 mm, outside diameter of 100.0 mm, and width of 21.0 mm, weighing 0.726 kg. The outer ring has two ribs and the inner ring has one rib with an internal rib washer, corresponding to the NUP design. The bearing is fitted with a polyamide cage (TVP2) and features the reinforced E design for increased load carrying capacity. Limiting speed is 10000 1/min, with a reference speed of 5800 1/min. The C3 radial internal clearance provides additional internal space to compensate for thermal expansion during operation, making this bearing suitable for applications with elevated operating temperatures or interference fits. As a locating bearing, it constrains axial movement in both directions while allowing free axial displacement of the non-locating bearing on the same shaft. The polyamide cage design supports smooth roller guidance at the stated speed ratings, and the open construction requires external sealing and a separate lubrication arrangement suited to the operating conditions.
