High-Precision Pinion Gears – The Core Guarantee for Girth Gear
As the core transmission component of large gear rings, no matter steel casting pinion gears or forging pinion gears can all custom manufactured to meet your technical specifications. Designed as the ideal power transmission solution for mills and kilns, our pinions work in perfect harmony with girth gears to maintain consistent, trouble-free operation while minimizing downtime and maintenance costs.
Inspection: UT/MT Materials: 42CrMo4, 20MnCr5, or custom required Industries Served: Cement, Wind Power, Mining, Oil & Gas and so on Surface Treatment: Quenching and tempering heat treatment (Quenching and Tempering, Annealing, Normalizing, etc.) Selection Recommendations：ZG42CrMo+carburizing and quenching+UT full inspection is preferred（Mining/cement equipment)
Advantages
Premium Materials, Exceptional Durability Made from high-quality alloy steels (42CrMo4, 20CrMnTi) with deep carburizing & quenching (HRC58-62) for uniform hardness and 50% higher impact resistance. Optional ZG35CrMoV specialty cast steel for extreme conditions (e.g., ball mills, crushers).
Precision Machining, Perfect Meshing CNC gear grinding (DIN 3962 Class 5+) ensures tooth profile accuracy ≤0.015mm, reducing noise and vibration. Paired grinding with gear rings achieves ≥80% contact pattern and 98% transmission efficiency.
Customized Solutions, Flexible Adaptability Supports non-standard customization (Module M1-M30, diameter 200mm-3000mm), compatible with MAAG, FLENDER and other international gear ring systems. Special treatments: pre-hardening, coatings (Ni-plating/nitriding) to extend service life.
