C2 Group clearance only for bearings over ABEC-3 accurancy.
4. Vibration and Noise
The vibration and noise of bearing in four classes Z1, Z2, Z3 and Z4, It is measured by the instrument of S09-1, For special requirement, it is measured by BVT-1 and classified as V1, V2, and V3, The date are shown tables, different vibration & noise requirement should be menrioned in order.
