Main Models of Roller Bearings for Aluminum Rolling Mills

1. Hot Rolling Mill

Back-up rollers: four-row cylindrical roller bearings and double-row tapered roller bearings

Work roll: four-row tapered roller bearing or four-row cylindrical roller bearing and four-point contact ball and other axial positioning bearings

2. Casting and rolling mill

Four-row tapered roller bearings are mainly used, and double-row tapered roller bearings are also used. There is also a trend of changing tapered roller bearings to cylindrical roller bearings and positioning bearings combination.

3. Rough rolling, intermediate rolling, finishing cold rolling, are the same type of rolling mills, but with different rolling forces and rolling pass. The bearings they used are four-row cylindrical roller bearings and axial positioning bearings.

Back-up rollers: four-row cylindrical roller bearings and double-row tapered roller bearings
