Henan San Kuang Machinery Technology Co., Ltd. proudly presents our Stainless Steel 304 Gear Shaft – a precision-engineered component designed for demanding mechanical applications. Manufactured in our 10,000-30,000 square meter facility with over 51 skilled employees, each shaft is CNC machined to achieve a tight 0.2mm tolerance and a precise 10mm bore. This gear shaft combines the corrosion resistance of 304 stainless steel with the reliability required for high-cycle gear systems, ensuring long service life even in harsh environments. Our commitment to quality is backed by a comprehensive quality management system, and we serve clients across North America, Europe, Asia, and beyond.
The gear shaft is a critical component in power transmission and motion control systems. Our product is manufactured using advanced CNC turning and grinding processes, resulting in exceptional concentricity and surface finish. The 0.2mm tolerance ensures a precise fit with mating gears and bearings, reducing vibration and noise while improving overall efficiency. The 10mm bore is sized to accommodate standard shafts or couplings, and custom lengths are available upon request.
Key Features & Technical Specifications
- Material: Stainless Steel 304 – excellent corrosion resistance, suitable for food processing, chemical, and marine environments.
- Precision Tolerance: ±0.2mm on all critical dimensions, ensuring consistent performance.
- Bore Diameter: 10mm (0.394 inch) – standard for many industrial applications.
- Surface Finish: Ra ≤ 1.6μm after machining, reducing friction and wear.
- Hardness: Optional heat treatment available (e.g., case hardening) to increase wear resistance – customizable per your requirements.
- Straightness: Maintained within 0.05mm/m for shaft lengths up to 1000mm.
- Keyway: Can be added upon request – standard keyway sizes available.
- Threads: Optional internal or external threads can be machined to specification.

| Tolerance (Diameter) | ±0.2mm | Can be tightened to ±0.1mm on request |
| Bore Diameter | 10mm (H7 fit optional) | Custom bore sizes available |
| Overall Length | Custom (50mm to 2000mm) | Specify required length |
| Surface Roughness | Ra ≤ 1.6μm | Lower roughness available |
| Straightness | 0.05mm/m | Ensured by straightening process |
Advantages & Customer Benefits
- Corrosion Resistance: 304 stainless steel withstands moisture, chemicals, and temperature variations, making it ideal for food processing, pharmaceutical, and outdoor equipment.
- Precision Fit: The 0.2mm tolerance ensures minimal backlash in gear assemblies, improving torque transmission accuracy and reducing energy loss.
- Long Service Life: High-quality machining reduces wear points, and optional surface treatments can further extend lifespan.
- Customization Flexibility: We offer custom lengths, keyways, threads, and heat treatment – all tailored to your specific application.
- Cost-Effective: Our large-scale production capacity (10,000+ m² factory) allows competitive pricing without compromising on quality.
- Global Shipping: Shipped from major Chinese ports (Shanghai, Qingdao, Tianjin, Lianyungang) with reliable logistics partners.
Our gear shafts are used in a wide range of industries including agricultural machinery, automotive transmissions, industrial gearboxes, conveyor systems, and robotic arms. The 10mm bore is particularly popular for small to medium-sized gearboxes where space is limited. With an annual export value of US$2.5-5 million, we have established trust with clients across North America, Europe, Southeast Asia, Africa, and Oceania.
Frequently Asked Questions (FAQ)
Q1: What is the minimum order quantity (MOQ) for this gear shaft?
A: For standard sizes, MOQ is 50 pieces. For custom specifications, MOQ may be 100 pieces. Please contact our sales team for exact pricing based on your quantity.
Q2: Can you provide a sample before mass production?
A: Yes, samples are available. We can machine a few pieces for your evaluation. Sample cost and lead time depend on complexity – typically 5-7 working days.
Q3: How do you ensure the 0.2mm tolerance is maintained?
A: We use CNC lathes with in-process gauging and post-machining inspection with micrometers and CMM. Our quality system (ISO9001 certified) ensures every batch is checked.
Q4: What is the typical lead time for production?
A: For standard shafts, 15-20 days after order confirmation. For customized items, 20-30 days depending on complexity. Urgent orders can be expedited upon request.
Q5: Can you machine keyways or other features on the shaft?
A: Absolutely. We can add keyways (standard square or rectangular), cross holes, threads, and flats. Please provide a drawing or specify the dimensions.
Q6: Is the material traceable? Do you provide material certificates?
A: Yes, we source 304 stainless steel from reputable mills and can provide mill test certificates upon request. Our material is traceable to the original batch.
Q7: What packaging do you use for export?
A: Shafts are individually wrapped in oil-proof paper, then packed in wooden crates or cartons with foam inserts to prevent movement. For sea freight, we use moisture-proof packaging.
Q8: Do you offer a warranty?
A: Yes, we provide a 12-month warranty against manufacturing defects. If any issue arises due to our workmanship, we will replace or repair at no cost.
