Hansheng Automation (Dongguan) Co., Ltd. is one of the most experienced manufacturers and suppliers of custom helical gears in China. If you're going to wholesale bulk cost-effective custom helical gears made in China, welcome to get pricelist and quotation from our factory. Also, customized service and OEM&ODM service are available.
As a leading gear manufacturing OEM partner in China, Hansheng provides a diverse range of customized gear solutions. With ten years of technical experience in manufacturing high-precision planetary gearboxes (P0) and harmonic reducers, our gears feature excellent design, smooth meshing, quiet operation, and superior load distribution.
Why Choose Our Helical Gears?
Unmatched Smoothness & Silence
Unlike the abrupt impact of spur gears, our Helical Gears feature angled teeth that engage gradually. This results in significantly reduced vibration and noise, making them ideal for high-RPM applications and sensitive environments like medical operating rooms or library automation systems.
Extreme Durability & High Torque Capacity
The increased contact ratio of our helical design allows for higher load-carrying capacity compared to equivalent-sized spur gears. We utilize advanced Heat Treatment processes (Carburizing, Nitriding, Induction Hardening) to maximize surface hardness and core strength, ensuring a long service life under heavy stress.
State-of-the-Art Manufacturing: The "Hard Skiving" Advantage
We leverage top-tier equipment, including the Kashifuji Gear Skiving Machine KPS30. This allows us to perform "Hard Skiving"-finishing the gear teeth after heat treatment.
Result: We correct heat-treatment distortions to achieve ISO/DIN Level 5 accuracy.
Capability: Perfect for Small Module Helical Gears and complex geometries where traditional grinding wheels cannot reach (e.g., internal gears or gears near shoulders).
Fully Customized to Your Specs
We are not limited to off-the-shelf standards. As a dedicated Custom Helical Gear Manufacturer, we tailor every aspect:
Helix Angle: Optimized for your specific center distance and thrust load requirements.
Materials: From Alloy Steel (SCM415/440) and Stainless Steel to Engineering Plastics (POM/PEEK) and Bronze.
Modifications: Keyways, set screws, complex shafts, and weight-reduction holes.

FAQ
Q: What precision levels can you achieve for custom helical gears?
A: We standardly achieve ISO/DIN Grade 5 (equivalent to JIS Grade N5 or AGMA 11-12). Thanks to our advanced Kashifuji KPS30 Gear Skiving Machine, we can maintain this high precision even after heat treatment using "Hard Skiving" technology. Our capability is proven by our internal production of Harmonic Drives (backlash ≤10 arc sec) and Planetary Gearboxes (backlash ≤1 arc min).
Q: How do you handle gear distortion after heat treatment?
A: Heat treatment often causes gear teeth to deform. Unlike traditional shops that only use hobbing (which cannot correct hardened gears), we utilize Hard Skiving and Precision Grinding capabilities. This allows us to machine the gear teeth after they are hardened, correcting any distortion to ensure perfect tooth profile, pitch accuracy, and low-noise operation.
Q: What is your minimum order quantity (MOQ)? Do you accept prototype orders?
A: Our minimum order quantity is 5 pieces. But our service is very flexible, and we also support prototypes to help you validate your design. Although the unit cost of mass production (such as 50 or more pieces) is more advantageous, we are fully capable of handling single sample orders for our B2B partners.
Q: What quality documentation do you provide with the shipment?
A: Every shipment includes a comprehensive Dimensional Inspection Report and material certificates. For gear accuracy, we provide detailed charts showing Profile Error, Lead Error, and Pitch Error, generated by our dedicated Gear Inspection Machines.
Q: What file formats do you need for a quotation?
A: For the most accurate quote, please provide:
3D Models: STEP (.stp) or IGS (.igs) files.
2D Drawings: PDF files specifying critical tolerances, materials, heat treatment hardness (HRC), and accuracy class requirements.
Note: We are happy to sign an NDA (Non-Disclosure Agreement) before receiving your files to protect your intellectual property.
