The Application OF NACHI Bearings In The Metal Smelting Rolling Mill Industry

Creation On:2025/12/08

NACHI bearings are widely used in the rolling mills industry. Manufactured from high-purity bearing steel and utilizing advanced heat treatment processes, these bearings offer exceptional load-carrying capacity, wear resistance, and fatigue strength. They are extensively compatible with critical sections such as roughing mills, finishing mills, continuous casting roller tables, and coilers. This provides reliable assurance for steel enterprises to achieve stable, efficient, and continuous production.

Ⅰ.Bearing Types

The primary bearing type NACHI applies in the rolling mills industry is the Four-Row Tapered Roller Bearing.Four-row tapered roller bearings are used on the roll necks of rolling mills. Their design provides maximum load-carrying capacity within a confined space while facilitating inspection and maintenance. In some bearings with larger inner diameters, pin-type cages and hollow rollers are employed to maximize load capacity.
