Mill Bearing process

Design issues Four-Row Tapered Roller Bearings burning and many other factors, generally normal, and typical aluminum foil rolling mill angular contact bearings burning is a worldwide problem, which I personally think is very important lubricating oil mist lubrication slightly better point, there bearing mounting clearance problems.
In addition there are a number of factors baffle shaft and the bearing clearance problems, but also bending load bearing outer cylinder to bring change issues and so on, foreign SMS mills produced by the SKF bearings tapered and thrust bearings ʱ?? Also bearing outer ring spring buffers and the like.
1. The support is generally used in four-row cylindrical roller small roller bearings, the inner interference fit with the roll, installed after the general sleeve, fitted into the inner ring, within the ring as a benchmark cylindrical grinding roll, because it can not afford axis force, axial force generated during the Rolling mill bearings need to bear, it is generally used in a double row angular contact four row cylindrical roller bearings back to back, face to face with the double row tapered roller bearings, and thrust bearings and four-point angular contact ball bearings , domestic manufacturers Wazhou product better, foreign manufacturers are willing to better the parent of American Railroads.
2. Work roll bearings generally use four-row tapered roller bearings, its structure, its inner circle is moving with the roll, that is to say when the roll regrinding, bearing along with the bearing together removed itself bear certain axis force, so some small mills axial force is its own bear, and some larger, or high precision rolling mill, generally using axial force bearing.
