BEARING VIBRRATION AND BEARING NOISE

VIBRRATION AND NOISE

The vibration and noise of bearings are classilsied as three classes as Z1,Z2,Z3.lt is measured by the instrument of SO910-ll,For special requirment,it is measured by BVT-1 and classified as V1,V2,and V3 The data are shown as below.Customer need mark the requirement of vibration and nosie class on the order.

TOLERANCE DATA FOR VIBRATION OF SINGLE BEARING AND NOMINAL 3MM~60mm
