Henan San Kuang Machinery Technology Co., Ltd. proudly presents our Helical Gear Module Set, engineered with ISO 6 precision and a robust 55 HRC surface hardness, specifically optimized for 220V motor applications. As a trusted manufacturer with a 10,000+ square meter facility and over a decade of experience, we deliver gear sets that ensure reliable power transmission, reduced noise, and extended service life in demanding industrial environments. Our commitment to quality is reflected in every component, from material selection to final inspection.
This helical gear module set is designed to meet the rigorous requirements of modern machinery, providing smooth and efficient torque transfer. Whether used in speed reducers, conveyors, or automated systems, these gears deliver consistent performance under varying loads. The combination of ISO 6 precision and 55 HRC hardness guarantees minimal backlash and high wear resistance, reducing maintenance downtime and operational costs.
Key Features & Technical Specifications
- Precision Grade: ISO 6 – ensures accurate tooth profile and spacing for low noise and vibration.
- Hardness: 55 HRC surface hardness (case-hardened) – excellent wear and fatigue resistance.
- Material: Premium alloy steel (20CrMnTi, 40Cr, or equivalent) – high strength and toughness.
- Heat Treatment: Carburizing and quenching with tempering – deep case depth for long life.
- Surface Finish: Precision ground finish (optional) – further reduces friction and noise.
- Customization: Module, number of teeth, bore size, keyway, and face width can be tailored per your drawings.
- Motor Compatibility: Specifically designed for 220V AC motors – shaft alignment and torque ratings matched.
- Application Range: Industrial gearboxes, CNC machines, packaging equipment, textile machinery, and more.

Frequently Asked Questions (FAQ)
Q1: What does "ISO 6 precision" mean for your helical gear set?
A: ISO 6 is a precision grade that defines tooth profile, pitch, and runout tolerances. It ensures accurate meshing, resulting in low noise, minimal vibration, and consistent torque transmission. This grade is commonly used in industrial gearboxes where reliability is critical.
Q2: Can the gear set be used with motors other than 220V?
A: Yes, while the set is optimized for 220V motors, we can adjust the bore size, keyway, and shaft fit to accommodate motors of other voltages (e.g., 380V, 440V). Please provide your motor specifications for customization.
Q3: What is the typical lead time for a custom helical gear module set?
A: Standard lead time is 15-25 working days after drawing approval. For urgent orders, expedited production can be arranged subject to factory capacity. We ship via sea or air freight from our port network.
Q4: Do you offer samples for testing before mass production?
A: Yes, sample orders are welcome. We can produce a small batch (1-10 pieces) for functional testing. Sample cost and shipping are negotiable, and we will refund the sample fee upon quantity orders.
Q5: How do you ensure the quality of the 55 HRC hardness?
A: We control the carburizing and quenching process with precise temperature and time parameters. Each batch is tested using Rockwell hardness testers to verify surface hardness within 55±2 HRC. A hardness test report can be provided upon request.
Q6: What materials are used for these gears?
A: Our standard material is 20CrMnTi alloy steel, known for its good carburizing performance and toughness. We also offer 40Cr, 42CrMo, or stainless steel options depending on corrosion or high-temperature requirements.
Q7: Can I request a specific module or tooth count not listed in the table?
A: Absolutely. Our production capacity covers modules from 0.5 to 20 and teeth numbers from 5 to 300. We use CNC hobbing and gear grinding machines to achieve high accuracy. Just send your drawing or specifications.
Q8: What packaging and shipping methods do you use?
A: Each gear set is individually wrapped with anti-rust oil, plastic film, and then packed in export-grade wooden crates. For small orders, we use cartons with foam inserts. We ship via FOB/CIF from Shanghai, Qingdao, Lianyungang, or Tianjin ports.
