The scraping range of hollow shaft bearing shells of vertical roller mills in smelters should be controlled at contact angle less than 35 according to the actual production requirements Below, it also needs to scratch clearance on both sides.

The spot distribution of contact should be distributed evenly and evenly along the whole length of bus, and there should be no excessive imbalance. The distance between spots should also have corresponding data requirements.

In the process of using the bearing bush, lubricating oil is an essential admixture, which is the key to ensure the normal operation of the bearing bush.
