Axial cylindrical roller bearings are part of the group of axial roller bearings. In contrast to the ball, the roller has a larger contact area perpendicular to the roller axis. As a result, it can transmit higher forces, has greater rigidity and allows smaller rolling element diameters under the same load. The single and double row bearings comprise flat, rib less washers (housing and shaft locating washers) between which axial cylindrical roller and cage assemblies are arranged. Their axial section height corresponds only to the diameter of the rollers plus the thickness of the washers. Due to this design, the bearings are particularly small in axial height. The axial cages are made from brass or plastic and are fitted with one or two rows of cylindrical rollers. Since sliding occurs towards the ends of the rollers during rolling of the rolling elements and this increases with the length of the roller, bearings with a wide cross-section have several short rollers arranged adjacent to each other. Single and double row axial cylindrical roller bearings are particularly suitable where: High axial and shock loads occur in one direction but no radial loads are present The load carrying capacity of the corresponding axial deep groove ball bearings is no longer adequate The bearing arrangement must have very high axial rigidity The axial space available is very small The bearing arrangement can be configured, where the axial space is very small, as a direct bearing arrangement The bearing parts can or must be mounted separately The bearing arrangement is not configured in itself but, for cost reasons, ready-to-fit standard bearings are to be used.
