NSK Thrust roller bearings for axial load mainly axial, radial joint load, but the radial load should not exceed 55% of axial load. With the other NSK Thrust roller bearings, such bearings lower friction coefficient, high speed, and with self-aligning performance. 29000 bearing .The stick-type spherical roller asymmetric, can reduce the roller and the raceway at work relative sliding and roller length, diameter, number of multi-roller, load capacity is high, usually oil lubrication, individual low-speed conditions can be used for grease lubrication. In the design selection, preference should be given;80000-type cylindrical roller thrust bearings, 90000-type thrust bearings and tapered roller bearings type AXK, can withstand a one-way axial load, thrust ball bearings than the axial load capacity is much greater, and rigidity, small axial space occupied.
Tapered roller bearings and thrust bearings for low speed applications, NSK Thrust roller bearings speed slightly higher than the thrust cylindrical roller bearings. Thrust cylindrical roller bearings are separable bearings, can withstand axial load and a slight impact, to limit the shaft (or shell) in one direction. The axial displacement, so can be used as a one-way axial positioning. But its carrying capacity is far greater than the thrust ball bearings. Roller rolling, because the roller ends of lines at different speeds, so that in the ring roller raceway sliding inevitably arise, therefore, such a bearing thrust ball bearing than the speed limit.
