One setup is 'locating and nonlocating', which uses two separate bearings on the main shaft. A locating bearing is exposed to both radial and axial loads, while a nonlocating bearing accommodates only radial loads. Other typical arrangements seen in large, modern turbines include: crosslocating tapered roller bearings, moment bearings ...

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.
