    Frequently Asked Questions
    Q What material is used in the external gear ring, and why is it superior to standard plastics?
    The external gear ring is made from German imported POM composite material enhanced through proprietary reinforcement technology. This results in a 60% increase in anti-creep performance compared to standard plastics, while retaining an ultra-lightweight density of just 0.15g/cm³ — making it ideal for precision and weight-sensitive applications.
    Q What module sizes and diameter ranges are available for the gear ring?
    The gear ring is available in module sizes of 0.5, 1.0, 1.5, 2.0, 2.5, and 3.0. The pitch circle diameter ranges from Φ20mm to Φ150mm, with a precision tolerance of ±0.02mm to ensure consistent performance across all sizes.
    Q What is the noise level of the gear ring during operation?
    Thanks to the five-axis NC machined helical gear profile with over 90% contact patch coverage, the gear ring operates at a noise level of ≤45dB under a 2000rpm working condition — suitable for environments requiring low-noise operation, such as medical equipment and office automation.
    Q What quality certifications and inspection processes are applied to each batch?
    Every batch undergoes full SPC (Statistical Process Control) monitoring throughout production, 100% CCD optical inspection of all critical dimensions, and comes with an SGS certification report. This ensures consistent quality and traceability for every order.
    Q Can the gear ring be customized to fit our existing gearbox design?
    Yes. We support 3D scanning reverse engineering services, allowing us to precisely measure and adapt the gear ring design to fit your existing gearbox. Custom modification samples can be produced and a prototype report issued within 48 hours of your request.
    Q What warranty and after-sales support is offered for bulk orders?
    Bulk orders are covered by a 12-month quality guarantee. In addition, we provide power transmission system simulation analysis — including service life prediction and thermodynamic simulation — to help customers validate system performance before full-scale deployment.
