This cylindrical roller bearing carries a full complement roller set in a single row, with 55.0 mm bore diameter, 100.0 mm outside diameter and 25.0 mm width. The outer ring has 1 rib and the inner ring has 2 ribs, giving the design designation A and forming a semi-locating bearing arrangement. Net mass is 0.847 kg, limiting speed 5000 1/min, reference speed 2700 1/min, with radial internal clearance in group CN (Group N). The full complement roller set gives higher radial load capacity for the given envelope size compared to a caged design, at the cost of a lower permissible speed. The semi-locating function, combined with the rib arrangement on both rings, allows the bearing to guide the shaft axially in one direction while accommodating axial displacement in the other, which is useful where a fixed-floating bearing arrangement is required. Standard CN radial internal clearance suits general mounting conditions with normal fits and moderate thermal expansion of the shaft relative to the housing.
