The pinion gear is a key component in a ball mill drive system, transmitting torque from the motor to the main girth gear to enable rotational movement. In heavy duty industries such as mining, cement, and metallurgy, ball mill pinion gears must deliver reliable performance under continuous operation and high loads.

At Belon Gear, we manufacture custom and replacement pinion gears for ball mills, engineered to meet demanding industrial requirements. Made from high-strength alloy steels such as 42CrMo or 35CrNiMo, our gears are heat-treated for enhanced wear resistance, hardness, and long service life.

Precision is critical to avoid vibration, noise, and gear failure. We produce pinions with DIN 7 to 8 class accuracy and optimized tooth profiles to ensure perfect mesh with girth gears. Our gear cutting, hobbing, and grinding processes are strictly controlled to guarantee concentricity and balance.
