This cylindrical roller bearing carries a full complement roller set arranged in a single row, with one rib on the outer ring and two ribs on the inner ring, giving it semi-locating function within the assembly. Bore diameter is 50.0 mm, outside diameter 90.0 mm, and width 23.0 mm, with a net mass of 608.2 g. The bearing reaches a limiting speed of 5500 1/min and a reference speed of 3000 1/min. The full complement roller arrangement increases the number of rolling elements in contact, raising radial load capacity within the given envelope, though it removes a cage and therefore limits the achievable speed compared to caged designs. Radial internal clearance is set to C3 (Group 3), allowing for thermal expansion under load. The semi-locating configuration permits axial displacement in one direction while providing guidance in the other, making mounting suitable where controlled axial float is required alongside high radial stiffness.
