Product Introduction
High-Strength Pinion Gear for Mining, Crushing & Industrial Drives
ZM INDUSTRY CO., LTD. manufactures high-precision pinion gears using premium 17CrNiMo6 alloy steel, offering models such as 12 tooth pinion gear, 20 tooth pinion gear, and fully customized pinion assemblies for industrial and mining equipment. The pinion acts as the primary driving element in power-transmission mechanisms, directly engaging with a ring gear to convert rotational motion into controlled torque output.
In mining machinery-including mills, crushers, conveyors, and hoisting systems-the pinion gear ensures synchronized rotation, efficient energy transfer, and minimal backlash. Its performance depends on tooth geometry, contact pattern, carburized hard-case depth, and surface roughness. Through optimized heat-treatment curves and CNC grinding, our gear pinion manufacturer capabilities deliver exceptional accuracy, ensuring reliable operation even in shock-load and high-torque environments.

Quality Control
Advanced NDT & Precision Inspection for Pinion Gears
Carburized Case Verification
Depth, hardness uniformity, metallographic structure, and tooth-surface quality are examined to guarantee extreme durability.
Ultrasonic & Magnetic Particle Testing
100% NDT eliminates internal cracks and latent defects, ensuring safe high-torque operation.
Dimensional Accuracy Control
CMM and specialized gauges measure runout, pitch deviation, and profile errors with micron-level precision.
Surface Roughness Inspection
Ground surfaces are evaluated to maintain low friction and stable meshing.
Heat-Treatment Validation
Complete quenching & carburizing curves ensure repeatable mechanical performance.
Rough Machining Flaw Detection
Early-stage ultrasonic screening prevents defective blanks from entering production, significantly improving reliability.
Packaging & Shipping
Global-Standard Packaging for Precision Pinion Gear Transport
ZM INDUSTRY CO., LTD. delivers export-grade packaging engineered specifically for high-precision pinion gears, pinion shafts, and complete gear and pinion assemblies. Each component is coated with anti-rust oil, wrapped with VCI film, and secured inside reinforced fumigation-free wooden crates. Customized internal bracing, vibration-absorbing pads, and locked mounting channels protect critical dimensions during long-distance shipment. To prevent moisture damage, every crate includes humidity indicators, waterproof lining, and sealed corner protection. Barcodes and traceability labels ensure full tracking for OEM clients. Whether shipping 12 tooth pinion gears, 20 tooth pinion gears, or large bevel gear pinion units, our packaging system guarantees maximum protection for international transportation.
