Chinese Industry Standard for Bearing Vibration Test

JB/T 10187 – 2011

Rolling bearings – Specifications for
vibration (velocity) of deep groove ball bearings

 1. Scope

This standard stipulates vibration  (velocity)  specifications for deep groove ball bearings:

  • Boundary dimensions conform to standard GB/T 46042006
  • Radial clearance C0, C2 or C3
  • Bore diameter from 3mm to 120mm

 

Vibration grade “V” in this standard is basic requirements for general purpose bearings which usually adopted by manufacturers for production inspection and not marked on finish products. Grade V1, V2, V3, V4 and peak value grade VF3, VF4 apply for bearings with additional vibration requirements to be used for bearing manufacturers’ quality control and users’ acceptance inspection.

3. Term and definition

3.1 Peak value of rolling bearings vibration (velocity)
Maximum positive peak value of bearings vibration velocity in given time interval.

4. Symbols for grade

VF3: Bearing vibration (velocity)  average value less than V3 and peak value less than VP3.
VF4: Bearing vibration (velocity)  average value less than V4 and peak value less than VP4.

6. Technical requirements of bearing vibration test

6.1 Test results of grade specified single bearing with bore diameter from 3mm to 60mm should be less than vibration (velocity) limit values and peak values in table 1.

6.2Test results of grade specified single bearing with bore diameter from 65mm to 120mm should be less than vibration (velocity) limit values and peak values in table 2.
