Welcome to Henan San Kuang Machinery Technology Co., Ltd. – your trusted partner in precision gear manufacturing. As a professional manufacturer established in 2022, we operate a modern factory spanning 10,000–30,000 square meters with a dedicated team of 51–100 employees. Our annual export value of US$2.5 million to US$5 million reflects our global reach and customer trust. We proudly offer our Hardened 60HRC Precision Gear for Heavy Loads, a non-standard custom solution engineered to meet the most demanding industrial applications. With DIN 6 accuracy and exceptional durability, this gear is designed to deliver reliable performance under extreme conditions, making it an ideal choice for heavy machinery, transmission systems, and specialized equipment.
Our gears are crafted from high-quality alloy steels such as 20CrMnTi and 42CrMo, subjected to precise heat treatment including carburizing, quenching, and tempering to achieve a consistent hardness of 60 HRC. This ensures superior wear resistance and load-bearing capacity. Every gear is machined to DIN 6 accuracy, guaranteeing smooth operation, low noise, and minimal vibration even under heavy loads. As a non-standard custom product, we offer full flexibility in dimensions, tooth profile, module, number of teeth, and surface treatment to match your exact specifications.
Key Features & Technical Specifications
Hardness: 60 HRC (Rockwell hardness scale C) – provides exceptional surface hardness and core toughness for heavy-duty applications.
Accuracy: DIN 6 standard – ensures high-precision meshing, reduced backlash, and improved transmission efficiency.
Material Options: Alloy steels (20CrMnTi, 42CrMo, 40Cr, etc.) – offering excellent fatigue strength and impact resistance.
Heat Treatment: Carburizing + quenching + tempering – creates a hard case and tough core for optimal performance.
Customization: Non-standard design – we can produce gears with specific module, pressure angle, helix angle, bore diameter, keyway, and surface finish.
Load Capacity: Engineered for heavy loads – suitable for mining, cement, steel mills, wind turbines, and marine applications.
Surface Treatment: Blackening, phosphating, zinc plating, Dacromet, or as per customer request – enhances corrosion resistance.
Quality Control: 100% inspection using CMM, gear testers, hardness testers, and runout gauges to ensure consistent quality.
Typical Parameters (for reference, customizable)
| Parameter | Range / Value |
|---|---|
| Module (m) | 1.5 – 20 |
| Number of Teeth | 10 – 200 |
| Outside Diameter | Up to 2000 mm |
| Face Width | 50 – 500 mm (customizable) |
| Hardness | 55–62 HRC (60 HRC typical) |

Frequently Asked Questions
Q: What is the typical lead time for a custom gear?
A: Lead time depends on complexity and quantity. For a standard non-standard gear (e.g., diameter under 500 mm, simple profile), we can deliver in 4–6 weeks. Larger or more complex gears may take 8–10 weeks. We will confirm when you provide your drawing.Q: Can you guarantee the hardness of 60 HRC throughout the entire gear?
A: Yes, we perform case-hardening (carburizing) and quenching to achieve a surface hardness of 60 HRC with a case depth typically 1–3 mm. The core remains tough to absorb shocks. We provide a hardness test report with each batch.Q: Do you offer samples before mass production?
A: Absolutely. We can produce a sample for your approval. The sample cost is negotiable and may be refunded with a production order.Q: What is the minimum order quantity (MOQ) for custom gears?
A: MOQ is typically 1 piece for prototypes, and 10 pieces for production runs. However, we are flexible and can discuss based on your needs.Q: Can you match DIN 6 accuracy for gears larger than 1000 mm diameter?
A: Yes, our machining capabilities allow us to maintain DIN 6 accuracy even for large gears up to 2000 mm diameter. We use precision grinding and inspection to ensure compliance.Q: What materials do you recommend for heavy load gears?
A: For heavy loads, we suggest alloy steels like 20CrMnTi or 42CrMo, which offer excellent hardenability and toughness. You can also specify materials like 40CrNiMo or 18CrNiMo7-6. We will work with you to select the best material for your application.Q: Can you provide gear design assistance if I only have performance requirements?
A: Yes, our engineering team can design the gear based on your application parameters such as torque, speed, center distance, and operating conditions. Please share your requirements and we will propose a suitable design.
