滚动轴承是将运转的轴与轴座之间的滑动摩擦变为滚动摩擦，从而减少摩擦损失的一种精密的机械元件。滚动轴承一般由内圈、外圈、滚动体和保持架四部分组成，内圈的作用是与轴相配合并与轴一起旋转；外圈作用是与轴承座相配合，起支撑作用；滚动体是借助于保持架均匀的将滚动体分布在内圈和外圈之间，其形状大小和数量直接影响着滚动轴承的使用性能和寿命；保持架能使滚动体均匀分布，防止滚动体脱落，引导滚动体旋转起润滑作用。
大多数采用优质渗碳结构钢、耐冲击工具钢或调质结构钢。3．接触介质在有腐蚀性的介质中使用的轴承必须采用具有良好耐腐蚀性的耐蚀钢或合金钢制造。二．根据轴承的结构类型选择轴承零件结构较复杂，如外圈带安装挡边，而且承受较高的冲击载荷时，宜采用加工性能良好的渗碳钢；冲压滚针轴承外圈可采用08和10低碳钢（塑性好。限制轴的两方面的轴向位移。主要用于限制轴和外壳双向轴向位移的部件中双列角接触球轴承内、外圈之间的可倾斜性有限，允许倾斜角取决于轴承的内部间隙、轴承尺寸、内部设计及作用于轴承上的力和力矩，而大允许倾斜角应保证轴承内不会产生过高的附加应力。若轴承内、外圈之间存在倾斜角，将影响轴承的寿命。
