As a trusted manufacturer since 2014, Henan San Kuang Machinery Technology Co., Ltd. delivers precision-engineered CNC gear shafts designed for demanding industrial applications. With over 10,000 square meters of advanced production facilities and annual exports exceeding US$2.5 million, we specialize in components that enhance transmission durability and performance. Our gear shafts feature exceptional 55HRC surface hardness, ensuring reliable operation in heavy-duty environments while minimizing wear and maintenance costs.
This CNC machined gear shaft stands out through:
- Superior Material Integrity: Crafted from high-grade alloy steel with uniform microstructure for consistent load distribution
- Precision Engineering: CNC machining ensures tooth profile accuracy within ±0.01mm tolerance
- Enhanced Durability: 55HRC surface hardness achieved through controlled heat treatment processes
- Optimized Performance: Helical or spur gear configurations reduce vibration and noise in high-torque applications
Technical specifications include:
| Parameter | Standard Value | Custom Range |
|---|---|---|
| Shaft Diameter | 20-150mm | 10-500mm |
| Length | 100-1000mm | 50-3000mm |
| Load Capacity | 5-50 kN·m | Up to 200 kN·m |
| Surface Roughness | Ra 0.8μm | Ra 0.4-1.6μm |
Key advantages for your operations:
- 30% longer service life compared to standard shafts due to optimized hardening
- Interchangeability with major transmission systems reduces integration time
- Corrosion-resistant options available for marine or chemical environments
