lead and antimony, because of its good wear resistance, high plasticity, good running performance. What is meant by running fit here? Thank you!
That is, with the rotation of the shaft, it can produce a consistent shape
The main material is wear resistant material, during this period it is normal wear and tear, and the wear rate is small. At the normal stage of operation, generally speaking, it is not said that running is proper.
Refers to the ability to work with the spindle neck to adapt to the working environment, especially after the new model or operation has just started. After the running in period, the plain bearing and the shaft neck do not change together.
