Improving Method

To improve bearing installation Shi of actual tie precision, must using not makes bearing deformation of measurement method and measurement tool, on bearing of bore and outside round of tie surface size for actual of precision measurement, can will about diameter and OD of measurement project all be measured, and on measuring have data made full analysis, to this for according to , precision distribution for axis and seat hole of bearing installation parts of size. Actual measuring distribution of shaft and bore the appropriate dimensions and geometric shapes, and measure the same temperature conditions.
