This cylindrical roller bearing carries axial loads in a single direction and is built up from three components: cage and roller assembly K811, shaft washer GS, and housing washer WS. Bore diameter is 50.0 mm, outside diameter 70.0 mm, height 14.0 mm, and net mass 142.3 g. The cage, designated TV, guides the rollers and is combined with separate washers, allowing individual component replacement. Limiting speed is 4900 1/min and reference speed 1840 1/min, which sets the practical operating window for continuous running. Because the design uses separate shaft and housing washers, the bearing accepts axial load only and requires a separate radial bearing to locate the shaft. Fitting the washers correctly to the shaft and housing seats is essential, and lubrication with grease or oil should match the reference speed to keep operating temperature within limits.
