This axial cylindrical roller bearing carries pure axial load in a single direction through a set of cylindrical rollers running between a shaft washer GS and a housing washer WS, guided by cage K811 in polyamide execution TV. Bore diameter is 140.0 mm, outside diameter 180.0 mm, height 31.0 mm, and mass is 1.759 kg. The bearing accepts a limiting speed of 1800.0 1/min and a reference speed of 710.0 1/min. The separate washers and cage allow the bearing to be assembled onto the shaft and housing independently, which simplifies fitting and dismantling on installations with a fixed axial position. As a single-direction unit it must be paired with a bearing capable of guiding the shaft radially or of taking load in the opposite axial direction, since it does not accommodate radial loads or reversed thrust. The polyamide TV cage keeps the roller set light and reduces friction losses, and the bearing requires grease or oil lubrication supplied through the surrounding housing arrangement, as no integrated sealing or lubrication feature is present.
