This cylindrical roller bearing carries a full complement roller set arranged in two rows, giving it a high load-carrying capacity for its size. The outer ring has one rib and the inner ring has three ribs, forming a semi-locating bearing configuration. Bore diameter is 20.0 mm, outside diameter 42.0 mm, and width 30.0 mm, with a net mass of 193.14 g. Limiting speed is 11400 1/min and reference speed 7400 1/min. The full complement roller set increases radial load capacity but limits speed compared to caged designs, so the stated limiting and reference speeds should guide the operating range. Radial internal clearance is CN (Group N), suitable for standard fit conditions. The semi-locating design with the rib arrangement allows the bearing to guide the shaft axially in one direction while accommodating free axial movement in the other, useful where controlled positioning combined with thermal expansion compensation is required.
