In order to improve the actual mating accuracy at the time of the bearing installation, the actual precision measurement of the inner diameter and outer diameter must be used to improve the measurement method and measurement tool of the bearing deformation, the inner hole and the outer circle of the bearing can be used. The project is all measured, and a comprehensive analysis of the measured data is made, according to this, precisely equipped with the size of the shaft and the bearing mounting portion of the seat. When the corresponding size and geometry of the actual measurements are equipped with the seat holes, it should be carried out under the same temperature conditions as measuring the bearing.
To ensure high actual cooperation, the shaft and seat holes are matched with the bearing surface, and the roughness should be as small as possible.
