This cylindrical roller bearing carries axial loads in a single direction, built up from the K811 cage-and-roller assembly together with the GS housing washer and WS shaft washer. Bore diameter is 80.0 mm, outside diameter 105.0 mm, height 19.0 mm, and net mass is 386.4 g. The cage is designated TV. Limiting speed is rated at 3100 1/min, with a reference speed of 1170 1/min. The three-piece design (K811 cage assembly, GS housing washer, WS shaft washer) allows the components to be mounted separately, giving flexibility in axial arrangement during assembly. Since the bearing accommodates axial load in one direction only, it must be paired with a suitable radial bearing to support radial loads in the assembly. The polymer TV cage guides the rollers and supports the specified speed ratings; no integrated sealing or lubrication is included, so lubricant supply and sealing arrangement must be provided by the surrounding construction.
