(Appendix of the standard)
Method for measuring vibration velocity of deep groove ball bearings with an inner diameter of 3+9mm The vibration (velocity) measurement method of deep groove ball bearings with an inner diameter of 3+9mm is as follows: After the automatic device is driven automatically, when the test bearing is not installed, the vibration of the sensor installation instrument shall comply with the provisions of Table A1 Table A1
Standard vibration s
50-300Hz
> 300--18001
b) The tolerance between the mandrel and the inner hole to be measured is -0.01m
) The speed of the dynamic shaft is IBoas/min+36rinuin
