Spiro Gear
Tired of trading company markups, communication gaps, and inconsistent batch quality in your motion control supply chain? Spiro Gear is the transparent, direct-from-source China factory you’ve been looking for. We engineer and manufacture world-class precision micro drives directly from our manufacturing floors to your global assembly lines under strict, repeatable quality control.
Deep industry heritage ensuring stable automated production lines and long-term supply security for global OEMs.
Every single motor is subjected to automated dynamic balancing and acoustic tests under real industrial loads.
We customize shafts, integrated encoders, and specialized gearheads to fit your device housing perfectly.
Fully compliant with international ISO9001, CE, RoHS, and REACH safety standards for worry-free import.
In the next decade, waterproof motors are moving beyond simple gaskets. Spiro Gear is investing in advanced vacuum impregnation and encapsulation technologies that allow motors to operate at depths of up to 100 meters (IP69K). Our roadmap includes:
The demand for "Silent & Waterproof" drives is expected to grow by 14% CAGR, driven by the rise of AI-powered outdoor robotics, automated pool cleaners, and specialized surgical tools.
Our manufacturing facility in China integrates high-precision machinery with automated workflows to ensure maximum efficiency.















Waterproof micro motors for electric shavers, hair clippers, and kitchen automation where humidity resistance is non-negotiable.
Heavy-duty worm gear motors for vending machines, coffee systems, and conveyor belts requiring high torque and longevity.
Precision 10mm motors for personal care devices, ensuring quiet operation and complete fluid ingress protection.
High-efficiency motors for robotic lawn mowers and pool cleaning equipment designed for harsh weather exposure.





Our lab is equipped with Video Measuring Instruments, Digital Oscilloscopes, and Magnetic Powder Testing Machines to verify every technical specification provided to our clients.
Navigating international trade requires more than just a good product. Spiro Gear ensures all products are CE, RoHS, and REACH certified. We provide comprehensive documentation for customs clearance, ensuring your supply chain remains uninterrupted by regulatory hurdles.
Our localized support includes 24/7 technical consultation for engineering teams in Europe, North America, and Southeast Asia.
Our standard waterproof motors reach IP67. However, for specialized underwater or heavy-washdown applications, we can engineer custom solutions that meet IP68 and IP69K standards using vacuum sealing and epoxy potting.
Yes. As an OEM factory, we specialize in non-standard shaft lengths, D-cuts, cross-holes, and custom mounting brackets to ensure the motor fits perfectly into your existing design.
We use automated production lines for winding and assembly. Every batch undergoes statistical process control (SPC) and 100% functional testing, including noise levels and torque-load curves.
Standard modifications usually take 2-3 weeks. For completely new designs involving custom gear molds, the timeline ranges from 6-8 weeks depending on complexity.
