推力球轴承采用高速运转时可承受推力载荷的设计,由带有球滚动的滚道沟的垫圈状套圈构成。由于套圈为座垫形,因此,推力球轴承被分为平底座垫型和调心球面座垫型两种类型。另外,这种轴承可承受轴向载荷,但不能承受径向载荷。该类轴承只适用于承受一面轴向负荷、转速较低的机件上,例如起重机吊钩、立式水泵立式离心机、千斤顶、低速减速器等。轴承的轴圈、座圈和滚动体是分离的,可以分别装拆。

Thrust ball bearings are designed to withstａnd thrust loads at high speeds, consisting of gasket rings with ball rolling raceway grooves. Because the ring is cushion, therefore, thrust ball bearing is divided into two types: flat bottom cushion type and center adjusting spherical cushion type. Besides, the bearing can bear axial load, but it can't bear radial load. This kind of bearing is only suitable for the parts with one axial load and low speed, such as crane hoisting hook, vertical pump vertical centrifuge, Jack, low speed reducer and so on. Bearing rings, seat rings and rolling bodies are separated, and they can be assembled and disassembled separately.
