In order to improve the the actual accuracy when the bearing mounting must not bearing deformation measurement methods and measuring tools, the actual size of the mating surfaces of the bearing bore and cylindrical precision measurement, the measurement of the inner and outer diameters the project measured all of them, and make a comprehensive analysis of the measured data, this data, the precision worthy of bearing shaft and housing bore size of the installation site. When the actual measurement with the corresponding size and geometry of the shaft and housing bore should be in the same temperature conditions in the measuring bearing. To guarantee higher actual blending effects, the shaft and the housing bore, with the bearing surface of the mating, the roughness should be as small as possible.
In making the above measurements, it should be on the outer and inner bore of the bearing, as well as the corresponding surface of the shaft and the housing bore, at the sides close to the chamfer, respectively, made mark showing the maximum deviation of the direction of the two groups, in order to in actual assembly, the maximum deviation of the match between the two parties is aligned with the same orientation, so that after assembly, the two sides of the deviation can be partially offset by.
Make the purpose of the two sets of directional signs, that the deviation compensation into account, even if both ends support each rotation accuracy improved, and they get between the two bearing housing bore concentricity error, and both ends of the journal part eliminated. Implementation of surface hardening measures, such as sandblasting, plug once inside the hole with a diameter slightly larger than the precision plunger mating surfaces are conducive to improving the fitting accuracy.
