This cylindrical roller bearing carries axial loads in a single direction, built up from three components: the K811 roller and cage assembly, the GS housing washer and the WS shaft washer. Bore diameter is 15.0 mm, outside diameter 28.0 mm, height 9.0 mm, and net mass 21.3 g. The cage is made in TV design. Limiting speed reaches 13400 1/min, with a reference speed of 6300 1/min. Being a single-direction axial cylindrical roller bearing, it locates a shaft against axial displacement in one direction only and must be paired with a radial bearing for radial support. The three-part construction allows the washers to be mounted separately, simplifying installation and adjustment of axial position. Its compact section height and the given speed ratings make it suitable where axial loads are combined with limited installation space.
