Henan San Kuang Machinery Technology Co., Ltd. is a professional manufacturer specializing in high-performance gear solutions. With a factory area of 10,000–30,000 square meters and a dedicated team of 51–100 employees, we have been delivering precision components since 2022. Our Spur Helical Gear 20CrMnTi Carburized 58-62HRC Module 1.5-6 is engineered to meet the demanding requirements of high torque transmission systems, offering exceptional durability and reliability.
This gear combines the advantages of spur and helical tooth profiles, providing smooth engagement, reduced noise, and high load-carrying capacity. Manufactured from premium 20CrMnTi alloy steel and subjected to a controlled carburizing and quenching process, it achieves a surface hardness of 58–62 HRC while maintaining a tough core. The module range of 1.5 to 6 makes it suitable for a wide variety of industrial applications, from heavy machinery to automotive transmissions.

Product Features & Benefits
- High Torque Capacity: The combination of spur and helical teeth allows for greater contact ratio, distributing load evenly and enabling transmission of high torque without premature failure.
- Enhanced Wear Resistance: Carburizing creates a hard wear-resistant case (58–62 HRC) while maintaining a tough core, significantly extending service life even under heavy loads and abrasive conditions.
- Improved Noise & Vibration: Helical tooth engagement reduces impact and noise compared to pure spur gears, making this gear ideal for applications where smooth, quiet operation is required.
- Versatile Module Range: With modules from 1.5 to 6, we can accommodate both small precision drives and large industrial gearboxes. Custom modules are available upon request.
- Superior Fatigue Strength: 20CrMnTi steel, combined with controlled heat treatment, provides excellent resistance to bending fatigue and pitting, ensuring long-term reliability.
- Precision Manufacturing: We use advanced CNC hobbing, shaping, and grinding equipment to achieve tight tolerances (AGMA 8–10 quality level), ensuring consistent performance in every batch.
- Customizable Design: Helix angle, tooth count, bore size, keyway, and other parameters can be tailored to your specific transmission requirements. Contact our engineering team for assistance.

Frequently Asked Questions (FAQ)
-
What is the difference between this gear and a standard spur gear?
This gear combines spur and helical tooth profiles, offering higher contact ratio, lower noise, and better load distribution than a pure spur gear. It is ideal for applications requiring both high torque and smooth operation. -
Can you provide gears with modules outside the 1.5–6 range?
Yes, we can customize modules from 0.8 up to 12 or more, depending on the design. Please contact our sales team with your specific requirements. -
What is the typical lead time for this gear?
Lead time depends on quantity and customization. For standard modules (1.5–6) without special features, typical delivery is 15–25 working days. For custom designs, please allow 25–40 working days. -
Do you provide heat treatment certification?
Yes, we can provide material certificates, hardness test reports, and heat treatment process records upon request. -
What packaging is used for export?
Gears are individually wrapped with anti-rust oil, then packed in wooden crates or cartons with foam cushioning to ensure safe transit. Ocean freight packaging follows international standards. -
Is this gear suitable for automotive transmissions?
Yes, the 20CrMnTi material and carburized hardness make it suitable for high-torque automotive drivetrains, such as truck gearboxes and heavy-duty vehicle transmissions. However, please verify your specific application parameters with our engineers. -
What is the minimum order quantity (MOQ)?
For standard modules, MOQ is typically 10 pieces. For custom designs, MOQ may be higher; please contact us for details. -
Can you supply gears with a hardness of 60–62 HRC instead of 58–62?
Our standard carburizing process achieves 58–62 HRC. If a tighter range (e.g., 60–62 HRC) is required, we can adjust the process parameters, but this may affect lead time and cost. Please discuss with our technical team.
