Full complement of cylindrical rollers is arranged in a single row inside this bearing, giving high radial load capacity within a compact cross-section of 25.0 mm bore, 52.0 mm outside diameter and 18.0 mm width. The outer ring carries 1 rib and the inner ring 2 ribs, forming a semi-locating arrangement (design A) that allows limited axial displacement while guiding the roller set. Net mass is 175.5 g, limiting speed reaches 10300 1/min and reference speed is 5500 1/min. The semi-locating design lets this cylindrical roller bearing take up axial float on one side of the shaft while still providing radial guidance, which suits arrangements where a matching bearing handles axial location. Radial internal clearance is class CN (Group N), the standard clearance range for normal operating conditions. As a full complement design without a cage, it offers increased load capacity per unit volume compared to caged variants, at the cost of a lower permissible speed. Open design requires external sealing and separate lubrication with grease or oil suited to the application's speed and temperature.
