5 measurement method
   
5.1 residual magnetic measurements using a Hall-effect principle, the measuring instrument must have
1mT the range and precision of plus or minus 3%. The instrument is equipped with a Hall element
specifications for 4 * 2 * 0.2 cubic meters, and the Hall element plane and the measured distance from
the surface of plus or minus 0.05mm.
   
5.2 for radial ball bearings, the measurement site for both ends and chamfering. Maximum readings
obtained for the measurement of the value of the residual magnetic bearings.
   
5.3 For cylindrical roller bearings, needle roller bearings, spiral roller bearings, tapered roller bearings and thrust roller bearings, measure its detachable parts should be separated. Addition to the
inner and outer rings (or seat, shaft washer) end and chamfer the measurement site should also measure the exposed parts of the rolling elements, such as rolling body residual magnetic parts in a cage at the
junction of the rolling elements may be appropriate rotation so that the parts measured after exposing.
 
For these bearings can not be separated type of measurement methods, in accordance with the provisions
of 5.2.
   
5.4 Spherical roller bearings, measuring both ends and chamfering at the reference to the provisions of 5.2. Measuring the rolling body to be within a radial plane of the outer ring into each 90 degrees. The rolling body measuring 5.3 on the rolling body measurements.
   
5.5 Thrust ball bearings, separable washers should be separated measurement, measurement site for
the seat, shaft washer end and chamfer. For these bearings can not be separated type of measurement methods, in accordance with the provisions of 5.2.
   
5.6 measuring bearing face residual magnetic probe vertical position of the end face of the bearing, measuring residual magnetic bearing chamfering and rolling elements, the probe can be used for appropriate recorded tilt, but not more than 45 degrees inclination.
