- JB/T 10187-2000.
Rolling bearings - Specifications for Vibration (Velocity) of
Deep Groove Ball Bearings
1 Scope
This standard specifies the specifications for vibration (velocity) of deep groove ball
bearings (hereinafter referred as bearings) of which the appearance dimensions comply
with provisions of GB/T 276-1994; diameter series are 0, 2 and 3; nominal inner diameter
is 3 mm ~ 120 mm; radial clearances comply with Group 0, 2 and 3 clearances as
specified in GB/T 4604-2006. And it specifies the vibration (velocity) peak-value
specifications corresponding to Group V3 and V4, and the inner diameter is 3 mm ~ 60
mm.
Group V specified in this standard stands is the basic requirements to common bearing
vibration (velocity). The bearing is not marked with “V”. Group V1, V2, V3 and V4 are
applicable to those bearings that have requirements to vibration (velocity). Group VF3 and
VF4 are applicable to those bearings that have requirements to both vibration (velocity)
and vibration (velocity) peak-value.
This standard is applicable to production inspection and user acceptance inspection for
finished bearings by manufacturer.

3 Terms and definitions
For the purpose of this standard, the following terms and definitions AND those defined in
GB/T 24610.1-2009 apply.
3.1
Peak-value of rolling bearings vibration (velocity)
The maximum positive peak-value of bearing vibration (velocity) within a given time
interval.
4 Group code
Following vibration group codes and the ones specified in JB/T 2974-2004 apply to this
standard.
VF3. Vibration (speed) value reaches V3 and vibration (velocity) peak-value reaches VP3.
VF4. Vibration (speed) value reaches V4 and vibration (velocity) peak-value reaches VP4.
5 Measurement and assessment method
5.1 Assessment method follows the provisions in Annex A.
5.2 In accordance with specified measuring method, select three roughly equidistant
positions on cylindrical outside surface of bearing outer ring in peripheral direction. During
the test of certain measuring plane, arithmetic mean of vibrations at three positions of
some frequency band is the vibration (velocity) value of the measuring plane for this
frequency band of the bearing. Maximum vibration (velocity) peak-value at three positions
of some frequency band is the vibration (velocity) peak-value of the measuring plane for
this frequency band of the bearing. After both sides are tested, take the vibration (velocity)
and vibration (velocity) peak-value of the larger side as the vibration (velocity) and
vibration (velocity) peak-value for this frequency band of the bearing.
6 Technical requirements
6.1 For deep groove ball bearings of which the inner diameter is 3 mm ~ 60 mm, single
bearing vibration (velocity) or vibration (velocity) peak-value of different groups shall
comply with provisions in Table 1.
6.2 For deep groove ball bearings of which the inner diameter is 65 mm ~ 120 mm, single
A.3.3 Test procedures
A.3.3.1 Test procedures shall follow provisions in 5.4 of GB/T 24610.2-2009.
A.3.3.2 Test duration shall follow provisions in 6.5 of GB/T 24610.1-2009. If it cannot
achieve a stable state within 5 min after the test is started, then the bearing shall be
deemed and handled as an unqualified product.

A.4 Measurement conditions
A.4.1 Bearing measurement conditions
Bearing measurement conditions shall follow provisions in 6.1 of GB/T 24610.2-2009. In
case of any objection against the test results of non-pre-lubricated bearings, NY-120
solvent oil is used to clean effectively. Test results after sufficient lubrication for L-AN15
total loss system oil shall prevail after solvent oil volatilizes and becomes dry. NY-120
solvent oil shall not contain tetraethyl lead and shall be filtered through a filter of which the
filtration precision is not less than 0.45 μm. L-AN15 total loss system oil shall be filtered
through a filter of which the filtration precision is not less than 0.8 μm. Other technical
requirements follow provisions of GB/T 3141-1994.
