1 Scope
This standard specifies the technical conditions of vibration (velocity) of single row tapered roller bearings with the nominal external diameter of 30mm~200mm.
Group V specified in this Standard is the basic requirements for the general bearing vibration (velocity); Group V1, V2 and V3 are applicable to the bearing with higher requirements for vibration (velocity). This Standard is applicable to the production inspection and user acceptance of taper roller bearings.
