Abstract：Review on shaft run-out calculation method has been preceded. Under stable working conditions, the calculation method can be classified into extremum method and confidence level method. Case analysis indicates that peak-to-peak values calculated from extremum method are not stable, and rely much on the filter selections. Peak-to-peak value calculation through 95% confidence level method was provided. Case research shows that under the 95% confidence level, when the calculation period is greater or equal to 6, peak-to-peak values calculated by 95% confidence level method will comes to convergence, and the convergence does not depend on whether the data has been filtered and the filter types. Four series peak-to-peak values comply with each other well.
