Thrust roller bearings are mechanical components primarily designed to withstand axial loads, capable of carrying a combination of axial and radial loads, with the radial load carrying value not exceeding 55% of the axial load.

This type of bearing has a low friction coefficient, can adapt to higher operating speeds, comes with automatic centering performance, and has good structural rigidity, occupying less space for axial installation.

The 29000 type bearing adopts an asymmetric spherical roller structure, which can reduce sliding friction, adapt to oil lubrication environments, and has good load bearing performance; 80000 type thrust cylindrical roller bearings, 90000 type thrust tapered roller bearings, and AXK type thrust needle roller bearings are suitable for low-speed operating conditions, can carry large axial loads, and achieve one-way axial positioning. Compared to thrust cylindrical roller bearings, thrust tapered roller bearings have stronger load-bearing performance and relatively lower maximum operating speeds.

Common supporting equipment includes heavy-duty machine tools, high-power marine gearboxes, oil drilling rigs, hydroelectric generators, crane hooks, etc.
