The roll bearing of the rolling mill is very important and is the core component for the normal operation and normal rotation of the roll. The working environment of rolling mill bearings requires it to have large bearing capacity, strong impact resistance, and unstable working temperature, so it is necessary to choose suitable bearings to reduce the downtime of rolling mill failures.
The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where ...

Roller Bearings Information. Roller bearings are used to replace sliding movement with low friction, rolling motion in rotary applications. The principal types of roller bearings are cylindrical, spherical, and tapered. In general, roller bearings offer higher load capacities than ball bearings of the same size.
The bearing, typically a roller or a plain bearing, allows for smooth rotation of the mill shell. It handles the considerable loads generated during operation. The trunnion seal, on the other hand, prevents contaminants from entering the bearing area, ensuring its longevity and performance.
Bearing selection examples. This section contains several worked examples that show the bearing selection process applied to various machines and application cases. Each example is presented as a number of steps that generally follows the sequence in the bearing selection process. However, interdependencies in any particular application case ...
