The case-carburizing process produces a hard, fatigue-resistant surface and a tough, crack-resistant core. Material composition and microstructure play a significant role in enhancing bearing life. Controlled retained austenite optimizes surface hardness of high-carbon steels and improves surface ductility, resulting in better rolling-contact fatigue life.

Tight manufacturing tolerances on the cup, cone and rollers help to optimize bearing life.

Advanced finishing processes result in more consistent, smoother surface finishes on our bearing races and rollers. Smoother surfaces finishes mean less friction and greater efficiency.

Special profiles reduce stress on Timken bearing races and rollers by providing more even distribution of loads across contact surfaces, increasing load-carrying capacity.

Timken provides customers around the world with high-quality steel. Capitalizing on the synergy between our bearing and steel businesses, we use our expertise to select bearing materials that meet the most demanding application requirements and help extend bearing life.
