Spiro Gear
Spiro Gear
Engineered to meet the tightest spatial tolerances and high torque demands of collaborative arms, smart locks, medical scanners, and automated service robots.
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. We engineer and manufacture precision micro drives directly from our manufacturing floors under strict, repeatable quality control.
Deep industry heritage since 2006, establishing highly stable automated production lines, tooling centers, and long-term supply security for worldwide robotics vendors.
Every single motor is subjected to automated dynamic balancing, vibration profile diagnostics, and acoustic testing inside soundproof chambers under real-world simulated loads.
We rapidly customize shaft configurations, integrated feedback encoders, special planetary ratios, and custom housings to fit your proprietary robotic drive envelope perfectly.
Spiro Gear leverages advanced Industry 4.0 infrastructure in China to deliver an uninterrupted supply of customized micro drive motors. By maintaining in-house raw material cutting, wire winding, gear hobbing, and automated housing injection, we minimize dependence on external sub-contractors.
Our deep vertical integration guarantees not only pricing advantages but also extreme batch consistency. From automated coil winding to laser micro-soldering, our digital tracking system monitors every stage of manufacture to provide comprehensive production accountability.
Our facility is equipped with state-of-the-art machinery capable of processing high-precision helical gears, shafts, and motor armatures to micron-level tolerances.

Our commitment to reliable performance means that we do not run a simple spot-check program. Instead, we operate an ISO-certified testing lab equipped with constant temperature chambers, salt spray cabinets, and soundproof acoustic rooms.
Every motor profile (torque-speed-current curve) is captured and saved to our tracking database. If you require specialized compliance documentation like CE, RoHS, or REACH, our engineering team provides complete verification dossiers with each batch.
As industrial automation and AI-driven service robots evolve, motor technology must become smaller, more power-dense, and smarter. Our R&D is focused on the next generation of micro motion control.

1. Integrated Smart Encoders & Drivers: The future of robotic actuation lies in the consolidation of components. We are actively developing micro brushless DC motors with integrated magnetic absolute encoders and drive circuits, allowing robot builders to reduce cabling and EMI interference.
2. High-Density Powder Metallurgy & PEEK Gears: To reduce noise and extend working life in AGV wheel drives and medical robotic joints, we are introducing hybrid gear assemblies utilizing hardened steel and precision-molded PEEK/POM gears. This ensures silent operation under 40dB without compromising load capacity.
3. Low-Backlash Strain Wave & Planetary Systems: For high-precision applications like cobot wrists and surgical instruments, we are refining our manufacturing process to limit standard planetary gearbox backlash to less than 0.2 degrees, offering precise path tracking at affordable production costs.
We do not compromise on reliability. Our manufacturing facilities are backed by an array of material testers, environmental chambers, and acoustic isolation rooms to ensure consistent batch performance.

For international buyers, navigating import compliance, customs clearances, and localized technical services is critical. Spiro Gear ensures seamless global logistics. We maintain pre-clearance status for EU and North American shipments and comply fully with ISO9001, CE, RoHS, and REACH safety standards.
Additionally, our sales engineering division provides real-time digital communication channels across multiple time zones. This eliminates communication delays and keeps your product design projects on schedule.
Get answers to critical technical and logistical questions when selecting micro motors for demanding robotic projects.
Planetary gearboxes distribute the torque load across multiple planet gears, allowing them to handle significantly higher torque outputs within a smaller footprint compared to spur gearboxes. This makes them ideal for robotic joints and tight physical envelopes.
We use advanced CNC gear-hobbing machines from Ningjiang and wire-cut EDM machinery to ensure tool clearances are kept within micron levels. This is combined with automated testing rigs that evaluate speed, current draw, and noise on every production run.
Yes. We regularly supply custom-designed units featuring specialized synthetic lubricants, high-grade permanent magnets, and sealed bearings suitable for harsh sub-zero temperatures, humid outdoor applications, or medical sterilization procedures.
Upon request, we provide detailed material safety data sheets (MSDS), declarations of conformity (CE, RoHS, REACH), dynamic performance test charts, and dimensional inspection reports from our internal metrology department.
