Ball Bearing & Tool Steels

Where Endurance Is the Only Metric That Matters.

In the world of high-wear components, failure is not a sudden event; it is a slow, grinding death that ends in the catastrophic seizure of a machine you depend on. This fate is determined by the fundamental integrity of the steel itself—an integrity we have spent half a century perfecting.

A Philosophy Forged in Friction

In the world of high-wear components, failure is not a sudden event; it is a slow, grinding death. It begins with microscopic pitting, escalates to premature wear, and ends with the catastrophic seizure of a machine you depend on. Every hour of that unscheduled downtime is a direct, unrecoverable loss. This fate is determined not in the final assembly, but in the fundamental integrity of the steel itself—an integrity we have spent half a century perfecting.

Exceptional Wear Resistance

Engineered to combat the constant punishment of abrasion & friction, drastically extending the component's lifespan.

Superior Surface Hardness

Achieves extreme hardness after heat treatment, thus preventing the scratches and scoring that lead to premature failure.

Excellent Fatigue Resistance

Designed with a clean microstructure to resist sub-surface cracking over millions of stress cycles.

Maintain Precision Shape

Offers high dimensional stability, ensuring com-ponents hold their exact tolerances for reliable operation.

The Marbrite Standard for Bearing Steels

For steels that must perform under constant punishment, 'close enough' is a guaranteed failure. The Marbrite Standard ensures that our bearing and tool steels possess a clean, homogenous microstructure free from the inclusions that lead to premature pitting and fatigue. We deliver fully traceable material with verified chemistry, providing the sound foundation required for a component that will not just operate, but outlast expectations.
