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。

　　Thrust ball bearings are designed to withstand thrust loads at high speeds and consist of gasket rings with ball rolling raceway grooves. Because the ring is a cushion, thrust ball bearings are divided into two types: flat base cushion and aligning spherical cushion. Besides, the bearing can bear axial load, but it can not bear radial load.

　　轴承特点 Bearing characteristics

　　备有单向、双向两种类型。

　　There are two types, one way and two way.

　　为了容许有安装误差，无论是单向还是双向，都可以选择球面调心球面座垫型或带球面座圈型。

　　In order to permit installation errors, either unidirectional or bidirectional, spherical centering spherical cushion type or with spherical seat ring type can be selected.

　　优质钢 ― 采用可使轴承寿命最高延长80%的超清洁钢。

　　High quality steel uses ultra clean steel which can extend the life of the bearing up to 80%.

　　高度的润滑脂技术 ― NSK的润滑剂技术可使润滑脂的寿命延长并提高轴承的性能。

　　High grease technology - NSK lubricant technology can prolong the life of grease and improve the performance of bearings.

　　高品位钢球 ― 高速转动时安静且顺畅。

　　High grade steel ball is quiet and smooth when rotating at high speed.

　　利用选件中的套圈，可容许有安装误差。

　　The use of rings in the option allows for installation errors.

　　轴承用途 Bearing applications

　　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。

　　It is only suitable for those parts which bear one side axial load and have low speed, such as crane hook, vertical pump, vertical centrifuge, jack, low speed reducer, etc. Bearing rings, seat rings and rolling bodies are detached and can be detached separately.
