What are the characteristics of thrust ball bearings and thrust roller bearings? Which one is better?
Compared with other thrust roller bearings, this kind of bearing has lower friction coefficient, higher rotating speed and better self-aligning performance. Thrust cylindrical roller bearings and thrust roller bearings are suitable for low speed applications. Thrust cone roller bearings have slightly higher rotational speed than thrust cylindrical roller bearings.Thrust cylindrical roller bearings belong to separate bearings, which can only bear one-way axial load and slight impact, and can restrict axial displacement of shaft (or shell) in one direction, so it can be used as one-way axial positioning. But its carrying capacity is far greater than thrust ball bearings. Roller rolling, the roller ends of lines at different speeds, the roller raceway in the ring sliding inevitably arise, therefore, such bearing limit rotational speed is low thrust ball bearings, usually only for low speed applications.
Thrust ball bearings generally have better centripetal performance, but they bear less thrust than thrust roller bearings.Thrust ball bearings are designed to withstand thrust loads at high speeds, consisting of washer shaped rings with raceways for rolling balls. Because the rings are cushion shaped, thrust ball bearings are divided into two types: flat seat cushion type and thrust thrust ball bearing, hheey heart spherical cushion type. In addition, this kind of bearing can bear axial load, but can not bear radial load.Thrust roller bearings can carry great loadsThrust roller bearings are used to bear axial load, axial load and radial joint load, but radial load should not exceed 55% of axial load.
Thrust ball is more suitable for the equipment with less carrying capacity, but the thrust roller has better performance in bearing capacity, high speed, noise and impact resistance.
