Thrust roller bearing series: 80000series, 29000series, AXK, AS00000series. Thrust cylindrical roller bearings are separable bearings which can only carry axial load and a slight one-way shocks, to limit the shaft (or shell) axial displacement in one direction, it can be used one-way axial positioning. But its carrying capacity is far greater than the thrust ball bearings. Because the roller ends of lines at different speeds, the roller ring raceway in the sliding inevitably arise, it usually only available in low speed situations
