Bearings for Steel Rolling Mills

Operating Conditions

Steel Mill Operating Conditions

Heavy Radial Loads

Rolling mill bearings must support high radial loads generated during steel deformation and roll contact.

Shock Loads & Vibration

Rolling impact, strip entry and process fluctuation can produce shock loads and vibration.

Heat, Water & Scale

Hot rolling environments may expose bearings to heat, cooling water, scale and contamination.

Precision & Rigidity

Cold rolling and finishing positions require stable rotation, high rigidity and controlled runout.

Continuous Operation

Steel rolling lines require reliable performance and short maintenance windows.

Products
