Bearing Vibration And Noise

2018-03-20

Bearing vibration and noise are divided into three levels, which are represented by Z1, Z2, and Z3. Measured with SO910-1 instrument. When there are special requirements, it can be detected by BVT-1, which is represented by V1, V2, and V3. The data is shown in the following table. Customers should mark the vibration and noise requirements when ordering.
