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 engineering plastics including POM (Crystal Steel) and PA66 (Nylon). Each material is selected based on its wear resistance, noise reduction, and load-bearing characteristics to suit your specific application scenario.
Q
What is the minimum and maximum size range for custom gears?
Our gears support an outer diameter range of 10–100mm, a modulus range of 0.1–2.5, and a tooth count from 3 to 100. This wide range allows us to accommodate both miniature and larger precision transmission requirements.
Q
What is the expected lifespan and durability of your double helical gears?
Our gears undergo rigorous life testing exceeding 500,000 revolutions with no abnormal wear detected. They operate reliably across a temperature range of -30℃ to 120℃ and produce noise levels below 45dB under standard working conditions.
Q
Can the helix angle be customized for specific transmission requirements?
Yes. We support helix angle customization from 0° to 35°, and our dual-connection structural design allows integration of straight and helical combinations in a single piece—enabling speed change or steering functions while reducing assembly complexity.
