  Measurement Before Bearing Installations

  When installing rolling bearings, the dial gauge should be fixed on the end face of the box shell first, so that the top of the contact head of the meter can migrate the transfer bearing on the raceway of the bearing shaft ring. While migrating the transfer, check the dial gauge pointer. If the pointer is swaying, it is clear that the shaft ring and the middle line of the shaft are not vertical.If the shell hole is deeper, y...

  How to Fit Tapered Roller Bearing Accuracy Design

  1. Tapered roller bearing system Under normal circumstances, the tapered roller bearing will use the base hole system when fitting, but if it is a standard part, the matching nature of the parts that match it is determined by the standard part. As for the tapered roller bearing, since it is a standard part, the part matching the outer ring is made of base shaft, and the shaft matching the inner ring is made of base hol...

  Bearing Operation Inspection And Operation Attention

  The inspection items during operation include the rolling sound, vibration, temperature, lubrication status of imported bearings, etc. The details are as follows: 1. The rolling sound of imported bearings uses a sound meter to check the size and sound quality of the rolling sound of the bearing in operation. Even if the bearing is slightly damaged such as peeling, it will emit abnormal and irregular sounds. Distinguish...
