We are repeatedly testing to ensure the accuracy of bearing
After bearing installed in the host, will be measured radially spindle runout, measured values can be found in each of its revolution has some changes; continuous measurements can be found after a certain number of revolutions after this change will be approximately repeated appear. This change is a measure of the degree of precision rotation cycle indicators, approximately repeated changes in the number of revolutions required on behalf of the rotation cycle accuracy "quasi-periodic", the magnitude of the change in the quasi-periodic large amplitude, rotation accuracy is poor circulation .
If properly pre-load on the spindle, the speed gradually increased to close to the operating speed, in order to implement "run" function of the bearing can be improved cycle rotation accuracy of the spindle.
