Hansheng Automation (Dongguan) Co., Ltd. is one of the most experienced manufacturers and suppliers of steel gear in China. If you're going to wholesale bulk cost-effective steel gear made in China, welcome to get pricelist and quotation from our factory. Also, customized service and OEM&ODM service are available.
Precision isn't just a word we use; it's what we build every day on the factory floor you see in the photo. For over 10 years, we have focused on manufacturing custom Steel Gears that do more than just connect parts-they ensure your equipment runs smoothly.
We don't just cut metal; we use advanced equipment to reach ISO/DIN Level 5 accuracy, making sure every gear is strong, silent, and incredibly durable. Whether for a high-speed robot or a heavy-duty packaging line, we craft our gears to deliver high performance that lasts much longer.
Products Features and Advantages
Guaranteed Precision Standards
Our steel gears are manufactured to meet ISO/DIN Grade 5 accuracy. This ensures high-level consistency and tight tolerances for every part, making them ideal for precision industrial automation and robotic applications.
Quiet & Smooth Transmission
By using specialized gear designs and precision finishing accurate to ±0.002mm, we significantly lower the noise and vibration during operation. This smooth meshing reduces friction and heat, helping your equipment run quieter and last longer.
Flexible & Fast Manufacturing
We offer diverse production methods to suit your project scale. For prototypes or small orders, our advanced CNC machining allows us to deliver high-quality gears quickly without the cost and time of mold making, ensuring a fast turnaround.
Full-Service Customization
From initial material selection and design optimization to final production, we provide a complete one-stop service. We can customize various types of gears-including spur, helical, and worm gears-to match your specific technical drawings and performance needs.

Applications
FAQ
Q: Can you manufacture gears based on my specific technical drawings?
A: Yes. We specialize in custom production. Just send us your drawings (STEP, CAD, or PDF) with details on tooth profile, modules, and tolerances, and our engineers will provide a technical review and quote.
Q: What is the typical lead time for a custom steel gear order?
A: For standard prototypes, it usually takes 7-10 days. For bulk production, the lead time is typically 3-4 weeks depending on the complexity of the heat treatment and finishing requirements.
Q: Do you provide material certificates and inspection reports?
A: Absolutely. We provide Material Mill Certificates and final QC inspection reports (including dimensional and hardness checks) with every shipment to ensure full traceability and quality.
Q: How do you ensure the gears don't rust during international shipping?
A: Every gear is treated with anti-rust oil and vacuum-sealed or wrapped in VCI (Volatile Corrosion Inhibitor) paper before being packed into sturdy wooden cases. This ensures they arrive in perfect condition.
