Mill bearing design problems, burning of rolling bearings and many other factors, generally normal, and the typical aluminum foil rolling mill angular contact bearings burning is a worldwide problem, which I personally think is very important lubrication, oil mist lubrication slightly better point, there are bearing mounting clearance issue.
Another damper shaft and bearing clearance problems, but also bending load bearing outer cylinder changes brought about problems, and so many other factors, foreign Simak mill produced by the SKF bearing cone and thrust bearings . There bearing outer ring spring buffer and so on.
1. Supporting rollers generally used four small cylindrical roller bearings, the inner ring with roller interference fit, usually installed after the sleeve, put the inner ring, circle within a cylindrical roll grinding basis, because it can not withstand the axis to the force produced during the rolling axial force required to bear bearings, generally used in a back to back double row angular contact ball bearings, double row tapered face roller bearings, and thrust bearings and four-point angular contact ball bearings, etc.
2. Work roll bearings generally use four tapered roller bearings, because of its structure, the inner ring is moving with the roll, that roll regrinding, the bearing removed together with the bearing, which itself can withstand a certain axis force, so some small mill which is itself bear axial force, while some of the larger or high precision mill, generally using axial force bearings.
We(GBZHB bearing company) supply many kinds of Mill bearings. If you have any interests, please contact me.
