Frequently Asked Questions
Order & After-Sales
Q Are the products compliant with industry standards for specific fields (e.g., automotive/medical)?
Absolutely. Our automotive-related products meet IATF 16949 requirements, and medical-use micro-transmission parts align with relevant medical device precision and safety standards—ensuring compliance with industry regulations.
Q Can SANI adjust product parameters (e.g., torque, speed) based on my application feedback?
Yes. After receiving your feedback on sample or trial use, our engineering team can optimize parameters like torque, speed, or material to better match your application needs.
Q What materials are available for custom double helical gears?
We offer a range of high-quality engineering plastics including POM (Crystal Steel) and PA66 (Nylon). Each material is selected based on its wear resistance, noise reduction properties, and suitability for specific load and environmental conditions.
Q What is the minimum and maximum outer diameter available for custom gears?
Our custom double helical gears support an outer diameter range of 10mm to 100mm, with a modulus range of 0.1–2.5 and tooth counts from 3 to 100, covering a wide variety of precision transmission applications.
Q What is the operating temperature range and noise level of your gears?
Our gears are engineered to operate reliably in temperatures ranging from -30℃ to 120℃. Noise levels are controlled to below 45dB, and durability is validated through life tests exceeding 500,000 revolutions with no abnormal wear detected.
Q Can a single gear piece achieve both speed change and steering functions?
Yes. Thanks to our structural innovation with dual-connection design, a single gear piece can integrate both straight and helical combinations, enabling speed change or steering functions simultaneously. This reduces assembly complexity and enhances overall transmission system reliability.
