Product Description
Customizable ZG 42CrMo Quenching and Tempering Large Size Gear Wheel
Heavy-duty girth gears are essential structural components for rotary drum applications. Our custom-made casting steel gear wheels are engineered for maximum durability and performance in demanding industrial environments.
Girth Gear Function and Maintenance
As a critical mechanical component, girth gears on rotary drums require immediate attention when wear occurs. While replacement is typically necessary for significant wear, early-stage wear can often be addressed through adjustments to prevent further damage.
Advanced Heat Treatment Process
Our gears undergo quenching and tempering heat treatment to achieve optimal hardness levels between 230-260 HB. Proper hardness of both girth and pinion gears is essential for maximizing equipment lifespan and performance.
Premium Material Selection
Manufactured from high-quality casting steel including ZG 42CrMo (AISI 4140) or ZG40CrNiMo (AISI 4340), ensuring superior strength and wear resistance.
