Bearing vibration and noise level can be divided into 4 levels: Z1, Z2, Z3 and Z4. We can detect by S0910-1 instrument. According to the special requirement, we can use BVT-1 detection, and be divided into the V1, V2, V3 and V4.Specific data are listed below. Customer’s order should be indicated the vibration and nosie level requirements.

The maximum vibration acceleration of single bearing. Tolerance dB
