Our Module 2.5 20CrMnTi Hardened Pinion Gear Assembly is specifically engineered for high-performance industrial gearboxes, offering exceptional durability and precision. As a leading manufacturer based in Luoyang, Henan, China, Henan San Kuang Machinery Technology Co., Ltd. has been serving global clients since 2014, with a factory spanning 10,000-30,000 square meters and an annual export value of US$2.5-5 million. We combine advanced manufacturing techniques with rigorous quality control to deliver pinion gear assemblies that meet the demanding requirements of various industries, including mining, cement, and power generation.
This pinion gear assembly is manufactured from 20CrMnTi alloy steel, a material known for its excellent hardenability and toughness. After precision machining, the gears undergo a carburizing and quenching heat treatment, achieving a surface hardness of HRC 58-62. This ensures superior wear resistance and fatigue strength, even under heavy loads and high-speed operations. The module 2.5 design provides an optimal balance of load capacity and compactness, making it suitable for a wide range of industrial gearbox applications.
Key Features & Technical Specifications
- Material: 20CrMnTi alloy steel – high strength, excellent impact resistance.
- Heat Treatment: Carburizing & quenching, followed by tempering, ensuring a hard case and tough core.
- Surface Hardness: HRC 58-62 (case depth 0.8-1.2 mm after grinding).
- Module: 2.5 – precise tooth profile for smooth meshing.
- Tooth Profile: Involute, ground to AGMA/DIN quality grades (Q6-Q8 available upon request).
- Customization: Number of teeth, bore diameter, keyway, and overall length can be customized.
