Hansheng Automation (Dongguan) Co., Ltd. is one of the most experienced manufacturers and suppliers of carbon steel gear in China. If you're going to wholesale bulk cost-effective carbon steel gear made in China, welcome to get pricelist and quotation from our factory. Also, customized service and OEM&ODM service are available.
At Hansheng Automation, we specialize in manufacturing high-precision carbon steel gears engineered for exceptional durability, cost-effectiveness, and reliable power transmission. Utilizing advanced 4-axis and 5-axis CNC machining, precision gear hobbing, and grinding equipment, we produce gears with module sizes ranging from 0.1 to 5.0 and achieve precision grades up to ISO/DIN Grade 5.
Whether you need medium carbon steel spur gears for robust industrial machinery or low carbon steel gears optimized for surface hardening, our engineering team delivers tailor-made components to meet your exact tolerances and application requirements.
Why Choose Our Carbon Steel Gears?
We don't just cut metal; we engineer solutions. By combining premium carbon steel materials (such as AISI 1045/S45C) with our ISO Grade 5 manufacturing capability, we solve the common pain points of noise, vibration, and premature wear.
Unmatched Precision
Achieving DIN/ISO Level 5 accuracy is our standard. Using the Kashifuji KPS30 Gear Skiving Machine, we minimize pitch errors and runout, resulting in Low Noise & High Torque transmission even at high speeds.
Superior Durability & Heat Treatment
Raw strength meets surface hardness. We provide in-house and specialized heat treatment options-including Carburizing, Quenching, and Induction Hardening. This ensures a wear-resistant surface (HRC 50-60 range) while maintaining a tough core to absorb shock loads.
Total Customization Flexibility
From prototype to mass production. We support custom designs for Spur Gears, Helical Gears, and Internal Ring Gears.

Materials & Heat Treatments
To achieve the optimal balance of toughness, wear resistance, and cost, we offer a select range of high-quality carbon steel grades coupled with specialized heat treatment processes:
Medium Carbon Steel (S45C / C45 / AISI 1045)
The most widely used material for industrial gears. It offers excellent machinability and responds exceptionally well to induction hardening, which significantly improves tooth wear resistance.
Low Carbon Steel (AISI 1020 / C15)
Ideal for gears requiring a ductile core and a hard wear-resistant surface. These are typically subjected to case hardening (carburizing) to withstand high shock loads.
Optional Heat Treatments:
- Normalizing
- Quenching & Tempering
- Induction Hardening
Our Manufacturing Edge: The "Power Skiving" Advantage
Why can we deliver higher precision than traditional hobbing shops? The secret lies in our investment in Gear Skiving Technology.
Unlike standard shaping or hobbing, our Kashifuji KPS30 allows us to:
- Machine Internal Gears and External Gears with equal precision.
- Perform Hard Skiving after heat treatment to correct any deformation, ensuring the final dimensional accuracy is locked in.
- Produce complex geometries close to shoulders or interference points that traditional cutters cannot reach.
This is the same technology we use to manufacture our high-precision Planetary Gearboxes (Backlash ≤ 1 arc min) and Harmonic Drives. We bring this Ultra-precision machining experience to your Carbon Steel Gear projects.
Applications
Our Custom Carbon Steel Gears are trusted by engineers in demanding industries:
Industrial Automation & Robotics: Actuators, joints, and precision rotary assemblies.
Packaging & Printing Machinery: High-speed, continuous-motion feed gears.
Textile & Agricultural Equipment: Reliable power transmission under moderate-to-high load environments.
Automotive & Precision Reducers: Planetary gearboxes and custom industrial gear reducers.
FAQ
Q: What is the highest precision level you can achieve for carbon steel gears?
A: We can achieve ISO/DIN Grade 5 (equivalent to AGMA 12/13). This is made possible by our Kashifuji Gear Skiving machine and our capability to perform hard finishing after heat treatment. This level of precision is suitable for high-speed robotics, servo applications, and precision reducers.
Q: Can you handle the heat treatment, or do I need to find a third party?
A: We provide a turnkey solution. We handle the entire heat treatment process, including induction hardening, carburizing, or nitriding. We take full responsibility for the final hardness and dimensional accuracy, saving you the risk and logistics of managing multiple vendors.
Q: My gear has a complex shape with a shoulder close to the teeth. Can you machine it?
A: Yes. This is exactly where our Power Skiving technology excels. Unlike hobbing, which requires a large run-out clearance, skiving allows us to cut teeth very close to shoulders or other interference features without damaging the part.
Q: Do you offer reverse engineering services if I don't have a drawing?
A: Yes. If you have a sample gear (even a worn one), we can use our CMM and Gear Inspection Machines to measure the parameters, deduce the original design intent (including profile shifts), and generate a new CAD drawing for manufacturing.
Q: What is your typical lead time for a custom order?
A: For prototypes or small batches, our typical lead time is 2-3 weeks. For mass production, it is generally 4-5 weeks, depending on the complexity of heat treatment and surface finishing requirements. We also offer expedited services for urgent maintenance replacements.
