BYB thrust needle roller and cage assembly or thrust cylindrical roller bearing is a set of roller pins (rollers) equipped with cages between a set of raceway washers. The cages reliably guide and hold a large number of rolling elements, and the rolling elements in the same assembly have only extremely small differences. BYB-Thrust needle roller bearings or thrust cylindrical bearings can only support axial loads in one direction, and can be used as a bearing configuration with good rigidity and minimal axial occupancy. Bearing configurations can be extremely compact if the surface machine of adjacent components can serve as a raceway for the needle roller and cage thrust assembly. If this scheme cannot be implemented, using the AS series gasket combination can also achieve a small axial section height with sufficient support space. The combination with thicker LS, GS, WS, ZS series gaskets is equally effective in applications where different requirements are required. Suitable AS, LS, GA, WS, ZS series gaskets must be ordered separately.
