Vibration and Noise

According to its accuracy Grade of the vibration value of the Noise of SL Bearing (Vibration)it is to be divided in Z1,Z2,Z3three groups.It can also be in accordance with Speed Grade of Vibration Value (m/s) V1V2V3 Groups to measure its vibration.(to see table 1.) If users have no requirement for vibration.The Normal Grade Bearing usually to be leaving out of the factory is in Vibration Value of Z1 Group.

Bearing Vibration speed Grade can not be over the following Values(dB)
