Rolling Elements for Heavy-duty Bearings

Application

Application Challenges

Extreme Loads

Heavy-duty bearings carry very high radial, axial and moment-related internal loads.

Shock & Vibration

Mining, construction and metallurgical equipment create repeated impact and vibration.

Contamination

Dust, scale and process particles can damage roller surfaces.

Low-speed Heavy Duty

Many heavy machines rotate slowly under high contact stress.

Long Service Cycles

Downtime is costly, so rolling elements must maintain geometry and surface quality.

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.
