    ✅ Quality & Performance
    🏅 What quality certifications support SANI's product reliability?

    Our management system complies with IATF 16949:2016 (certificate No.: D462458, valid until Nov 19, 2025), ensuring strict quality control from design to production — suitable for automotive, medical, and high-precision industries.

    🔬 How does SANI ensure the precision of gears and gearboxes?

    We use high-precision processing equipment (e.g., AgieChamilles wire-cutting and EDM machines) for mold manufacturing, plus Japanese Osaka gear meshing instruments and OGP plane testers for quality inspection — guaranteeing consistent precision.

    🛡️ Can the products withstand harsh environmental conditions?

    Yes. We minimize product risks through strict quality management, ensuring reliability even in harsh environments (e.g., high/low temperatures, vibration) for automotive, outdoor security, and industrial scenarios.

    ❓ Frequently Asked Questions
    Q What is the difference between the POM plastic version and the metal powder metallurgy version?
    The POM plastic version offers lightweight design, low noise, and is ideal for light-load applications such as smart home devices. The metal powder metallurgy version delivers significantly higher torque — up to 60,000 gf.cm instantaneously — making it suitable for industrial automation and heavy-duty scenarios.
    Q What voltage options are supported by SANI gearbox motors?
    SANI gearbox motors support both 12V and 24V voltage inputs, providing flexible compatibility for a wide range of applications including smart home systems, industrial equipment, and medical devices.
    Q How quiet is the gearbox during operation?
    Through optimized tooth profile design and high-precision assembly processes, noise levels are controlled within 30dB during normal operation. This makes the gearbox highly suitable for noise-sensitive environments such as medical equipment and smart home applications.
    Q Can SANI gearboxes be integrated with different motor types?
    Yes. SANI gearboxes are designed with broad compatibility in mind. The total length dimensions (L1 for gearbox and L for overall) can be flexibly matched, supporting direct integration with both stepper motors and DC motors.
    Q Are SANI products suitable for medical device applications?
    Absolutely. SANI products are used in infusion pumps and operating bed adjustment mechanisms. Combined with IATF 16949:2016 certification and rigorous quality control, they meet the reliability and precision demands of the medical industry.
    Q What is the speed accuracy of SANI gearbox motors under load?
    Under rated load conditions, the speed error is maintained at ≤5%, ensuring stable and consistent torque output. For example, a 4:1 reduction ratio delivers a reliable 947.2 gf.cm torque output for demanding applications.
