Penn Machine is a major supplier of traction gearing to the world’s railroads. Our carburized and hardened "Super Gear", a premium product, is now recognized as the standard in the railroad industry. Costs saving reprofiling services utilizing Cubic Boron Nitride Grinding technology are offered for GE, EMD and ALCO gears.

The Penn Machine "Super Gear" is the only gear in the industry with a five-year limited wear warranty.

The triple alloy "Super Gear" is carburized and hardened and Cubic Boron Nitride finish ground. When compared to some induction heat treating methods, carburizing provides a better, more consistent hardness through the effective depth resulting in exceptional wear properties. CBN (cubic boron nitride) finish grinding adds beneficial compressive stress in the tooth surface compared to conventional aluminum oxide grinding. The "Super Gear" technology has become the standard in the industry.
