As a leading manufacturer based in Luoyang, Henan, China, Henan San Kuang Machinery Technology Co., Ltd. has been dedicated to the production of high-quality transmission components since 2014. Our Transmission Gear Shaft with Carburized Surface Treatment is engineered to deliver exceptional durability and performance under heavy loads. With a 10,000-30,000 square meter factory and over 50 skilled workers, we combine advanced heat treatment technology with precision machining to ensure every shaft meets the highest standards. This product is ideal for automotive, industrial, and agricultural applications where reliable power transmission is critical.
Our gear shafts are manufactured using premium alloy steels such as 20CrMnTi and 20CrMo, which are then subjected to a controlled carburizing process. This case-hardening technique creates a wear-resistant outer layer (HRC 58-62) while maintaining a tough, ductile core. The result is a component that resists fatigue, pitting, and bending, even in demanding environments. Below are the key technical specifications:
| Parameter | Value |
| Material Grade | 20CrMnTi, 20CrMo, 8620, 4320, etc. |
| Carburized Layer Depth | 0.8 – 1.5 mm (customizable) |
| Surface Hardness | HRC 58-62 |
| Core Hardness | HRC 30-40 |
| Diameter Range | 20 mm – 200 mm |
| Length Range | 100 mm – 2000 mm |
| Tooth Accuracy Grade | DIN 6-7 / ISO 6-7 |
| Surface Roughness | Ra ≤ 0.8 μm |
Key Features & Benefits:
- Superior Wear Resistance: The carburized surface treatment significantly extends the service life of the gear shaft, reducing downtime and maintenance costs.
- High Fatigue Strength: The combination of a hard case and tough core resists bending fatigue and tooth breakage even under cyclic loading.
- Precision Engineering: All shafts are machined with CNC gear hobbing, shaping, and grinding equipment to ensure tight tolerances and smooth operation.
- Customizable Designs: We offer custom dimensions, spline types, keyways, and internal bore configurations to meet specific OEM requirements.
- Rigorous Quality Control: Every batch undergoes hardness testing, metallographic analysis, and dimensional inspection to ensure consistency.
- Versatile Applications: Suitable for manual and automatic transmissions, transfer cases, differentials, planetary gear sets, and industrial gearboxes.
Our manufacturing process follows strict quality management systems. We have obtained certifications including ISO9001, TS16949, QS9000, ISO14001, and OHSAS18001, which are available upon request. The factory is equipped with more than 50 advanced machines, including vertical/horizontal gear hobbers, shapers, and heat treatment furnaces. With an annual export value exceeding US$2.5 million, our products are trusted by clients in North America, South America, Europe, Southeast Asia, Africa, and the Middle East. We ship from major ports such as Shanghai, Lianyungang, Qingdao, and Tianjin.
