Thrust roller bearings for axial load mainly axial, radial joint load, but the radial load should not exceed 55% of the axial load. Other thrust roller bearings, such bearings lower friction coefficient, high speed, and aligning performance.
29000, bearing stick asymmetric spherical roller, the roller can reduce the relative sliding and rolling in the work, and the roller length, large diameter roller quantity, high load capacity, usually oil lubrication individual low speed available greased. In the design selection, should be preferred;
80000-type cylindrical roller thrust bearings, 90000 Thrust tapered roller bearings and needle roller thrust bearings AXK type, can withstand a one-way axial load, it is much larger than the thrust ball bearing axial load capacity and rigidity, small axial space occupied.
Thrust cylindrical roller bearings and thrust roller bearings for low speed applications, thrust tapered roller bearing 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 axial displacement (or shell) in one direction, and therefore can be used as a one-way axial positioning. But its carrying capacity is far greater than thrust ball bearings. Roller rolling, because the roller ends of lines at different speeds, so that the rollers in the ring raceway sliding inevitably arise, therefore, such bearing speed limit lower than the thrust ball bearings, normally only for low speed applications.
Standard design thrust cylindrical roller bearings with machined metal solid cage, according to user requirements, but also other types or materials cage. Thrust tapered roller bearings can withstand axial load, can limit the axial displacement of the bearing, it can be used as a one-way axial positioning. And thrust cylindrical roller bearings compared to carrying capacity, relative sliding is small, but the lower speed limit.
Thrust cylindrical roller bearings are mainly used for heavy-duty machine tools, power marine gear boxes, oil rig, vertical motors and other machinery.
