Scope

This standard specifies the vibration (velocity) technical conditions of the N-type, NU-
type, NJ-type, NF-type cylindrical roller bearings, whose external dimensions conform
to GB/T 283-2007, which have a diameter series 2 and 3, a nominal inner diameter of
15 mm ~ 120 mm, a radial clearance conforming to group 0 clearance specified in GB/T
4604-2006 (hereinafter referred to as bearings).
Group V specified in this standard is the basic requirement for vibration (velocity) of
general-purpose bearings. "V" is not marked on the bearings. Groups V1, V2, V3 are
suitable for bearings that require vibration (velocity).
This standard applies to the production inspection and user acceptance of finished
bearings by the manufacturer.

Summary	This standard specifies the dimensions meet the N -type GB/T 283-2007 prescribed, NU type, NJ type and NF type, diameter series 2, 3, nominal inner diameter of 15mm ~ 120mm, radial clearance in line with GB/T 4604-2006 0 set forth in clearance of cylindrical roller bearing vibration (velocity) technical conditions. This standard specifies the V group is the basic requirement for universal bearing vibration (velocity). Bearing no mark "V", V1, V2, V3 group suitable for vibration (velocity) has requested bearings. This standard applies to factory for the production of the finished bearings and user acceptance testing.
