Aluminum Industry

Rolling aluminum is fundmental process for aluminum industry. Sheet, plate and foil are usually made by rolling thick aluminum between rolls that reduce the thickness and lengthen it. Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallization temperature, then the process is termed as hot rolling. If the temperature of the metal is below its recrystallization temperature, the process is termed as cold rolling.

Usage of Suntree Bearings in Aluminum Industry:

In the hot rolling process, the angular adjustment of the chocks in rolling mills allows the use of four-row tapered roller bearings and multi-row cylindrical roller bearings to bear radial loadings. The design of the radial bearings depends on the specific application. In general, angular contact ball bearings for rapidly rotating rolls under low axial load, double-row tapered roller bearings and axial spherical roller bearings for high axial loads.
Cold rolling process results in a higher dimensional accuracy, surface quality and smaller sheet thicknesses. Our four-row cylindrical roller bearings fulfill the high demand for precision, even in high-speed rolling mills for aluminum. In multi-roll mills for stock that is difficult to roll, cylindrical roller bearings can be used as back-up roller systems and ensure uniform sheet thickness and surface quality under extremely high loads.
Making bearings for aluminum industry is one of our core businesses for more than twenty years. Our application and design engineers understand the needs of our customers and are willing to cooperate with our clients to make the high quality of bearings as demands.
