Welcome to Henan San Kuang Machinery Technology Co., Ltd. – your trusted partner for large diameter, high precision ring gears up to 2000 mm outer diameter. As a professional manufacturer established in 2022 with a 10,000–30,000 square meter factory and an annual export value of US$2.5–5 million, we specialize in delivering customizable module ring gears that meet the most demanding industrial applications. Our gears are designed for durability, accuracy, and seamless integration into heavy machinery, wind turbines, mining equipment, and more. With a strong team of 51–100 skilled employees and multiple certifications including ISO9001, ISO14000, and OHSAS18001, we ensure every product meets rigorous quality standards.
Our large diameter ring gears are engineered to handle extreme loads and harsh environments. The gear teeth are precisely cut using advanced CNC gear hobbing and shaping machines, achieving precision grades up to ISO 7 (DIN 7). We offer a wide range of materials such as 40Cr, 42CrMo, and 20CrMnTi, with optional heat treatments like carburizing, nitriding, and induction hardening to enhance surface hardness and wear resistance. Each gear is fully customizable – from the outer diameter, inner diameter, bore, keyways, to mounting holes and tooth profile (straight, helical, or involute).
Key Features & Benefits:
- Large Diameter Capability: Up to 2000 mm OD, suitable for heavy-duty applications.
- High Precision: ISO 7–9 (DIN 7–9) ensures smooth operation and low noise.
- Customizable Module: Module range from 1 to 50 mm, tailored to your design.
- Durable Materials: High-grade alloy steels with optional heat treatment for extended service life.
- Flexible Customization: OD, ID, tooth profile, bore, keyway, and mounting holes all configurable.
- Comprehensive Testing: 100% dimensional inspection, hardness test, and magnetic particle inspection available.
