VIBRATION AND NOISE |
The vibration and noise of bearings are classified in four classes Z1,Z2,Z3, AND Z4, it is measured by the ins trument of SO910-1. For special requirement, it is measured by BVT-land classified as V1, V2, V3, and V4.
The data are shown in below tables, different vibration & noise requirement should be mentioned in order. |
