Established in 2014, Henan San Kuang Machinery Technology leverages its 10,000-30,000 sqm production facility to engineer precision custom couplings for heavy-duty industrial applications. Our couplings are specifically designed to withstand extreme operational stresses in mining, manufacturing, and energy sectors, featuring mill test verification for guaranteed material integrity. With $2.5M-$5M annual exports to global markets including North America and Europe, we combine advanced manufacturing with rigorous quality control.
Core Technical Advantages:
- Torque Optimization: Engineered to transmit up to 500,000 Nm without deformation
- Misalignment Compensation: Accommodates angular, parallel, and axial misalignments up to 5°
- Vibration Dampening: Reduces gearbox wear by 40% through proprietary flange design
| Parameter | Standard Range | Custom Options |
|---|---|---|
| Bore Diameter | 100-300mm | 50-500mm |
| Operating Temp | -20°C to 150°C | -40°C to 300°C |

Each coupling undergoes rotational balance testing at 1,200 RPM and includes corrosion-resistant seals for harsh environments. The mill test documentation provides full traceability of material composition, heat treatment cycles, and mechanical properties.
With certifications including ISO 9001 and OHSAS 18001, our Luoyang-based facility ships globally through Shanghai, Qingdao, and Tianjin ports. Serving clients across 14 international markets, we maintain ≤0.02mm machining tolerances using CNC turning centers. Contact our engineering team for application-specific solutions that reduce maintenance costs by up to 35%.
