The Purpose of the Orientation Sign of the Two Groups of Bearings

When performing the above measurement, the outer circle and inner hole of the bearing should be made on both sides of the shaft and seat holes, respectively, and two sets of markers in the direction of the maximum deviation direction, respectively. When the actual assembly, the maximum deviation of the two parties is aligned, so after assembly, the deviation of the two parties is partially offset.

The purpose of the orientation marker for two sets of bearings is that the compensation of the deviation can be considering that both the respective rotation accuracy of the two ends have improved, but also make the two-socketing seat holes and two ends of the two-end journal Error Get partial elimination. Surface enhancement measures are implemented on the surface of the fitting surface, such as sandblasting treatment, with a slightly large sequester column plug in a diameter, etc., is conducive to improving the fitting accuracy.
