Talking about the vibration level and applicable range of the bearing

Core Tip: Bearing vibration (acceleration) is divided into four grades: Z, Z1, Z2, and Z3; bearing vibration (speed) is divided into four grades: V, V1, V2, and V3. Z, V grade is suitable for bearing manufacturer benchmarking
Bearing vibration (acceleration) is divided into four grades: Z, Z1, Z2, and Z3;


Bearing vibration (speed) is divided into four levels: V, V1, V2, and V3.

Z and V grades are applicable to the vibration test of deep groove ball bearings within the scope of the standard specified by the bearing manufacturer;

Z1 and V1 are applicable to the inspection of bearing products with general requirements for bearing vibration;

Z2 and V2 are applicable to Y series motors and other motor bearings with corresponding requirements;

Z3 and V3 are suitable for vibration requirements. This level has international advanced level
