1.Rolling Mill Bearing Features:

Rolling mill bearings are used in the rolling industry, ie rolling of non-ferrous metals, ferrous metals and non-metallic products. Used for rolling bearings at the roll diameter and on the drum. Four-row cylindrical roller bearings are commonly used to withstand radial loads, thrust roller or thrust ball bearings, and radial angular contact balls or radial roller bearings to withstand axial loads. Most of them are lubricated and cooled by oil-air lubrication or oil mist lubrication and grease.

2.Rolling Mill Bearing Structure Classification:

1. The support roller generally adopts four rows of cylindrical small roller bearings, and the inner ring is statically matched with the roller. After the cone sleeve is generally installed, the inner ring is fitted, and the outer circle of the roller is refined on the basis of the inner ring, because it cannot bear the shaft. The axial force generated during the rolling process needs to be bearing. Generally, double-row angular contact ball bearings with back-to-back, double-row tapered roller bearings with face-to-face, and thrust bearings and four-point angular contact ball bearings are used. Domestic manufacturers have better shaft products, and foreign manufacturers are better in the United States.

2. The work roll bearing generally adopts four-row tapered roller bearing. Because of its structure, the inner ring and the roller are in dynamic cooperation. That is to say, when the roll is re-grinded, the bearing is removed together with the bearing seat, and the bearing itself can bear a certain axis. Toward force, some small rolling mills have their axial forces that are themselves tolerated, while some larger, or more accurate, rolling mills generally use axially loaded bearings.

3.Rolling Mill Bearings Application:

The oil film bearing technology of rolling mill is a systematic engineering technology. At the same time, it is also a comprehensive engineering technology in a multidisciplinary field. Its development speed and supporting capacity reflect the development speed and level of Chinese industry from one aspect. From the main aspects of operation technology, manufacturing technology, testing technology, theoretical research, product development, and complete set of capabilities, we briefly discuss
