斯凯孚SKF轴承量规GRA30环规，适用于检测超高精密轴承的锥形安装面
SKF环规
GRA30环规
SKF的GRA30系列环规通常用于检测NN30K系列圆柱滚子轴承的锥形安装面。GRA30系列环规还可以用来检查NNU49BK和N10K系列轴承的安装面。
GRA30环规可用于d≤200mm的圆锥轴座。对于 d>200mm 的轴座，SKF建议使用圆锥量规。d>200 mm时，环规由于其自身重量不易操作。
SKF锥度量规
测量选项
GRA30系列环规主要用于确定锥形安装面相对于轴上基准面的位置。GRA30系列环规的基准面位于孔的大端。轴上基准面既可以在环规测量面之前，也可以在其之后。GRA30系列环规也可以用于检测锥形安装面的中心线是否位于轴基准面的正确角度。这是通过测量环规基准面与轴基准面间的距离来实现。
锥体的形状误差可以利用蓝色染料来检查。
锥形安装面尺寸
SKF建议为 NN30 K 系列轴承使用以下产品表中列出的圆锥轴座尺寸。

如果采用其他尺寸或者轴承系列，则参考长度Bc应始终大于Bb，中间隔圈的宽度。因为根据轴承应达到的内部游隙或预载荷，轴承安装面上推进的距离要长于环规。因此，要确保参考长度长于中间隔圈宽度，而且差值*小值应对应Bc–Bb（产品表）。
