Vibration Grade

In terms of vibration, GBM deep groove ball bearings fall into groups V, V1, V2 V3 by vibration velocity gauge and / or groups Z, Z1, Z2, Z3, Z4 by vibration acceleration gauge.

Z & V: For general applications. Standard deep groove ball bearings in compliance with GB are in these groups.
Z1 & V1: For applications where there are primary requirements for vibration.
Z2 & V2: For Y electric motors or equivalent where there are special requirements for vibration.
Z3 & V3: For applications where there are strict requirements for vibration.
