This standard specifies the technical requirements, measurement methods, evaluation methods and inspection rules for the vibration (velocity) of deep groove ball bearings of diameter series 0, 2, 3 (hereinafter referred to as bearings) with the nominal external diameter greater than 10 mm to 200 mm and the boundary dimensions conforming to GB/T 276.
This standard is applicable to deep groove ball bearings. Group V specified in this standard is the basic requirement for vibration (velocity) of general bearing; Groups V1, V2, V3, V4 and VF3, VF4 are applicable to the bearings with higher vibration (velocity) requirements, and Groups VF3 and VF4 group are only applicable to the bearings with a nominal external diameter of more than 10 mm to 100 mm.
