The robust design of our girth gear minimizes downtime and maintenance costs. The normalized microstructure ensures dimensional stability even under fluctuating thermal conditions, while the hard surface layer resists abrasive wear from ore and grinding media. Our gear hobbing process produces teeth with excellent profile accuracy, leading to uniform load distribution and reduced stress concentrations. This directly translates to longer service intervals and lower total cost of ownership for your equipment.
