This cylindrical roller bearing carries axial loads acting in a single direction, with a bore diameter of 25.0 mm, an outside diameter of 42.0 mm and a height of 11.0 mm. The set is built up from three components: cage and roller assembly K811, housing washer GS and shaft washer WS, with a net mass of 51.6 g. The cage TV positions the rollers, and the bearing is rated for a limiting speed of 8600 1/min and a reference speed of 3500 1/min. The single-direction axial design means the bearing must be mounted together with a radial bearing to guide the shaft, as it only takes thrust load from one side. The separate washers and cage assembly allow mounting and dismounting of the components independently, and the roller and washer surfaces require lubrication with grease or oil suited to the reference and limiting speed values given.
