Full complement of cylindrical rollers arranged in two rows carries radial loads across a bore diameter of 50.0 mm, an outside diameter of 80.0 mm and a width of 23.0 mm, giving a net mass of 418.66 g. The outer ring has 1 rib and the inner ring has 3 ribs, forming a semi-locating bearing, design A. Limiting speed is rated at 6100.0 1/min, with a reference speed of 3700.0 1/min. The full complement roller set increases radial load capacity within the same envelope compared to a caged design, at the cost of a lower attainable speed. Radial internal clearance CN (Group N) suits standard shaft and housing fits without additional adjustment. The semi-locating configuration allows axial displacement in one direction while guiding the shaft in the other, useful where shaft expansion due to temperature change must be accommodated without inducing axial preload.
