1 Scope
This standard specifies the technical specification for the vibration (velocity) of cylindrical roller bearing (hereinafter referred to as bearing) with radial internal clearance in accordance with Group 0 clearance specified by GB/T 4604-2006, of the Types A, Type, NJ and NF with diameter series 2 and 3, and nominal bore diameter 15mm~120mm specified in GB/T 283-2007.
Group V specified in this standard is the basic requirements for the general bearing vibration (velocity) without "V" marked on the bearing; Group V1, V2 and V2 are applicable to the bearing with requirements for vibration (velocity).
This standard is applicable to the manufacturer's production inspection and user acceptance of finished bearing.
