With specially designed raceways and rollers, thrust roller bearings are capable of achieving higher thrust with lower friction and better performance in self-regulation. able to withstand heavy axial loads in one direction and heavy radial loads at relatively high speeds. From the point of view of the inner design, the rollers have a shape fit with the raceway to distribute the load along the roller length. In other words, the load can be distributed between the raceways at an angle to the bearing shaft. On the other hand, the raceway of the thrust roller bearing is spherical with the radius center located on the bearing shaft. The design provides self-alignment with bearings.
