Henan San Kuang Machinery Technology Co., Ltd., established in 2014, specializes in high-precision transmission components. Our Aluminum Alloy Servo Motor Spider Coupling with Zero Backlash is engineered for applications demanding positional accuracy and torsional rigidity. Manufactured in our 10,000-30,000 sqm facility, this coupling integrates aerospace-grade materials with advanced elastomer technology to eliminate rotational play while dampening vibration. With over US$2.5 million in annual exports and ISO-certified processes, we deliver components trusted by automation integrators across five continents.
Core Technical Advantages:
- Zero Backlash Design: Achieves ≤0.1 arcmin angular transmission error through preloaded elastomer inserts
- Weight-Optimized Construction: 7075-T6 aluminum alloy reduces inertia by 40% vs. steel equivalents
- Triple-Layer Spiders: HNBR/Nitrile composite spiders maintain elasticity from -40°C to 120°C
- Torque Density: Transmits up to 380 Nm in compact 80mm OD packages
| Parameter | Standard Range | Custom Options |
|---|---|---|
| Bore Diameter | 6-40mm | Up to 120mm |
| Max RPM | 8,000 | 12,000 (balanced) |
| Parallel Offset Tolerance | ±0.5mm | ±1.2mm (extended spider) |
Operational Benefits:
- Improves robotic positioning repeatability by 92% vs. backlash-prone couplings
- Reduces servo motor current spikes through vibration absorption
- Maintenance-free operation for 20,000+ hours under normal conditions
With TL9000 and ISO16949 certified manufacturing, our couplings ship globally through Shanghai, Qingdao, and Tianjin ports. Serving 85% of North American robotics OEMs and Eastern European automation leaders, we provide:
- Custom bore keyways/splines per DIN 5463
- IP66 protection packages
- EMC shielding options
