Manufacturing Processes & Capabilities

• Φ9mm Ultra-Micro Planetary Tooling & Assembly: Houses a 1:180 multi-stage planetary gear system within an ultra-slim Φ9 mm cylindrical form factor; micro-tolerance tooling ensures precise tooth geometries and tight concentricity across sun, planet, and ring gears for minimal backlash.
• Flexible Material Pairing & Precision Packaging: Offers brass casing for high rigidity/shielding or ABS for lightweight requirements, combined with precision-molded POM, Nylon, or PE gears to balance mechanical strength and smooth running torque.

Features & Advantages

• High Reduction Ratio & High Torque Density: Slim envelope integrates easily into tight spaces, delivering steady 30 RPM output and 0.25 kg-cm torque to achieve substantial gear reduction in a miniature footprint.
• Low-Noise Transmission & Wear Resistance: Symmetrical multi-planet load distribution combined with self-lubricating polymer gears minimizes friction, dampens vibration, and ensures quiet, long-term durability.
• Standardized Versatility & Broad Compatibility: A versatile standard product line with customizable ratios, speeds, and torques that interfaces seamlessly with micro DC and stepper motors to shorten development cycles.
