江苏省苏州杰瑞轴承有限公司

推力球轴承由一列钢球（带保持架）、一个轴圈（与轴紧配合）和一个座圈（与轴有间隙而与轴承座孔紧配合）组成，钢球在轴圈和座圈之间旋转。只能承受一个方向的轴向载荷，不能承受径向载荷。由于轴向载荷是均匀地分布在每个钢球上，故载荷能力较大；但工作时，温升较大，允许极限转速较低。
　 推力球轴承是分离型轴承，根据其结构形式分为单向推力球和双向推力球轴承。单向推力球轴承可承受一个方向的轴向载荷，双向推力球轴承可承受两个方向的轴向载荷。它们均不能承受径向载荷。推力球轴承还有带座垫的结构，由于座垫的安装面呈球面形，故轴承具有调心性能，可以减少安装误差的影响。推力球轴承主要应用于汽车、机床等行业。型号有：NRB2X21,8-G2
