This cylindrical roller bearing carries axial loads in a single direction and is built up from three components: cage and roller assembly K811, housing washer GS, and shaft washer WS. Bore diameter is 20.0 mm, outside diameter 35.0 mm, and height 10.0 mm, with a net mass of 34.2 g. The cage, designated TV, is a polyamide roller-and-cage assembly. Limiting speed is rated at 10800 1/min, reference speed at 4300 1/min. The separate washer design allows the bearing to be mounted with the cage and roller set fitted independently between the shaft and housing washers, which simplifies assembly and alignment on the shaft and housing seating faces. As a single-direction axial roller bearing, it locates the shaft in one axial direction only and requires a separate radial bearing to support radial loads. No integral sealing is provided, so lubrication and contamination protection must be arranged externally at the installation stage.
