Henan San Kuang Machinery Technology Co., Ltd. proudly presents our Quenched Tempered Internal Gear Ring – a high-strength ring gear engineered specifically for speed reducer assembly. With over a decade of precision manufacturing experience and a 10,000-30,000 m² factory, we produce gear rings that deliver exceptional durability, wear resistance, and dimensional stability. This product is the core component for reducing vibration and ensuring smooth power transmission in demanding industrial applications.
Our internal gear rings undergo a rigorous quenched and tempered heat treatment process, achieving an optimal balance of hardness and toughness. This ensures reduced deformation under heavy loads and prolonged service life. Designed for easy integration into speed reducers, the gear ring offers high concentricity and precise tooth geometry, minimizing backlash and noise. Whether for new assemblies or replacement parts, our gear rings meet diverse customer requirements.
Backed by ISO9001 and other management system certifications, each ring is manufactured under strict quality control. We serve global markets including North America, Europe, and Southeast Asia, with annual export value exceeding 2.5 million USD. Choose our quenched tempered internal gear ring for reliable performance in your speed reducer systems.
Key Features & Technical Specifications
- Advanced Heat Treatment: Quenched and tempered process ensures hardness of HRC 58-62 with excellent core toughness, preventing premature tooth wear.
- High Strength Materials: Available in alloy steels like 20CrMnTi, 40Cr, or 42CrMo, offering superior tensile strength and fatigue resistance.
- Precision Machining: CNC hobbing and grinding achieve precision grades from DIN 6 to DIN 8, ensuring smooth meshing and low noise operation.
- Flexible Customization: Module from 1.5 to 10, tooth count from 20 to 200, inner/outer diameters tailored to your speed reducer design.
- Consistent Quality: 100% dimensional inspection and hardness testing per batch guarantee uniform performance.
- Surface Protection: Optional black oxide or phosphating coating provides corrosion resistance during storage and transport.

Advantages for Speed Reducer Assembly
Our quenched tempered internal gear ring directly contributes to the overall efficiency and longevity of the speed reducer. The high strength-to-weight ratio reduces parasitic loads, while the precise tooth profile minimizes energy loss. Customers benefit from lower maintenance frequency, reduced downtime, and consistent torque transmission even under cyclic loading.
Compared to standard untreated gears, the quenched tempered ring exhibits 30-50% higher wear resistance, extending the service interval of the entire assembly. The through-hardened structure also prevents surface pitting and case crushing, common failure modes in high-load applications.
