产品详情
该类轴承能够同时承受径向载荷和轴向载荷，也可以承受纯轴向载荷，能在较高的转速下工作。单列角接触球轴承只能承受一个方向的轴向载荷，承受轴向负荷的能力由接触角决定，接触角大，承受轴向负荷的能力高, 但接触角越小则越有利于高速旋转。接触角α的定义为，径向平面上连接滚球和滚道触点的线与一条同轴承轴垂直的线之间的角度。按接触角度的不同分为：
1、接触角α=15°，后置代号为C，多用于较大尺寸精密轴承，如7005C；
2、接触角α=25°，后置代号为AC或A5，多用于精密主轴轴承，如7005AC；
3、接触角α=30°，后置代号为A，多用于精密主轴轴承，如7005A；
4、接触角α=40°，后置代号为B，适用于承受较大的轴向载荷，如7005B；
