This cylindrical roller bearing carries a full complement roller set arranged in two rows, giving high radial load capacity within a compact cross-section of 40.0 mm bore, 68.0 mm outside diameter and 21.0 mm width. The outer ring has 1 rib and the inner ring has 3 ribs, forming a semi-locating design (type SL18, design A). Net mass is 310.0 g, limiting speed 7300.0 1/min, reference speed 4350.0 1/min. The full complement roller set increases the number of rolling elements, raising load-carrying capacity per unit volume compared to cage-guided designs. Radial internal clearance C3 (Group 3) provides increased clearance suited to compensate for tighter fits or thermal expansion during operation. As a semi-locating bearing, it allows limited axial displacement while still guiding the shaft radially, which is useful where controlled axial freedom is required without a separate locating bearing.
