Vibration And Noise
- Categories:Standards
- Time of issue:2019-11-22 00:00:00
- Views:0
The vibration and noise of bearings are classified in four classes as Z1,Z2,Z3 and Z4.It is measured by the instrument of SO910-1.For special requirement, it is measured by BVT-1 and classified as V1,V2 and V3. The data are shown in below tables. different vibration & noise requirement should be mentioned in order.
