Carries axial loads in a single direction through a single row of cylindrical rollers running between two flat washers, with a bore of 240.0 mm, outside diameter of 340.0 mm, and height of 78.0 mm. Net mass is 21.95 kg. The bearing is rated for a limiting speed of 990.0 1/min and a reference speed of 340.0 1/min, with a brass cage identified as M. The cylindrical roller and washer arrangement gives high axial rigidity and load-carrying capacity within a compact height, making the bearing suitable for pure axial loading where radial guidance is provided separately. The M cage supports stable roller guidance at the stated speed ratings, and the flat contact surfaces of the washers require adequate lubrication to maintain the rated reference speed under continuous operation.
