This cylindrical roller bearing carries a full complement of rollers in a single row, giving it a high radial load capacity within a compact cross-section. Bore diameter is 45.0 mm, outside diameter 85.0 mm, and width 23.0 mm, with a net mass of 569.9 g. The outer ring has one rib and the inner ring has two ribs, design A, forming a semi-locating arrangement. Limiting speed is rated at 6100.0 1/min, with a reference speed of 3450.0 1/min, and radial internal clearance is CN (Group N). The semi-locating design allows the bearing to accommodate axial displacement in one direction while guiding the shaft in the other, useful where some axial float must be permitted. The full complement roller set increases load-carrying capacity per unit volume compared to caged designs, though it requires suitable lubrication to manage friction between adjacent rollers. Radial internal clearance CN (Group N) suits standard operating conditions without significant preload requirements.
