同轴度公差和径向跳动公差是不同的。
Coaxiality tolerance and radial run-out tolerance are different.
结合图例和生产工艺论述了径向跳动公差与同轴度公差的关系、取代及工艺实施。
This article introduces relation, substitution and implement of radial run-out tolerance and axiality tolerance with legend and production process.
同轴度公差评估的是轴线相对于基准轴线的偏差，而径向跳动公差则评估的是圆周线相对于同轴圆的偏差。
The coaxiality tolerance assesses the deviation of the axis from the datum axis, while the radial run-out tolerance assesses the deviation of the circumference line from a coaxial circle.
因此，特征提取线的偏差受限于在任何方向的全跳动公差，而不是在任何方向的径向跳动（3.10）公差。
Therefore the deviations of the generator line of the toleranced feature are limited by the total run-out tolerance in any direction, but not by the circular run-out tolerance in any direction (3.10).
