This axial cylindrical roller bearing carries load in one direction only and is built up from three separate components: the K811 cage-and-roller assembly, the GS housing washer and the WS shaft washer. Bore diameter is 130.0 mm, outside diameter 170.0 mm, height 30.0 mm, and the set weighs 1.619 kg. The cage is designated TV. Limiting speed is 1920.0 1/min, with a reference speed of 760.0 1/min. Because the three rings are supplied and mounted separately, the bearing allows precise axial positioning and can be fitted with only the required washer contact surfaces machined into the housing and shaft. The single-direction design means it takes axial load from one side only, so it must be paired with a suitable radial bearing to locate the shaft and, if load reversal occurs, combined with a second axial bearing. No integrated sealing is provided, so lubrication and contamination protection have to be arranged through the surrounding housing design.
