Rolling Elements for Rolling Mill Bearings

Application

Application Challenges

Heavy Radial Loads

Rolling mill bearings operate under very high radial loads and repeated rolling forces.

Shock & Load Fluctuation

Rolling forces change with strip entry, speed, temperature and mill setup.

Contamination & Lubrication

Scale, coolant, water and particles can affect raceway and roller surfaces.

High Temperature & Speed

Hot rolling and high-speed mill stands create heat and centrifugal effects.

Replacement Accuracy

Repair projects require rollers to match existing raceways, cages and bearing geometry.

Products

Recommended Rolling Elements

Cylindrical Rollers

High radial load capacity, high rigidity and low friction. Diameter, length, end geometry and profile can be customized.

Tapered Rollers

Designed for combined radial and axial loads. Large-end diameter, small-end diameter, angle and end profile can be customized.

Spherical Rollers

Designed for self-aligning spherical roller bearing structures under heavy loads and misalignment. Curvature and geometry can be customized.
