The affect of inclination varying amount δD was analyzed on mounting dimension, ra-dial clearance and radial runout of the bearing. δD will directly affect life of the bearing. The six technol-ogy countermeasures for strictly controlling δD value have been provided.%就滚针轴承的外圈外表面素线对基准端面的倾斜度变动量δD值对轴承的安装尺寸、径向游隙及径向跳动所产生的不良影响进行了分析，并指出δD的增大将直接影响轴承的使用寿命，造成轴承失效。提出了严格控制δD值的6项工艺措施。附图4幅。
