Frequently Asked Questions

What is a gearbox reducer?

A reducer is an independent closed transmission device between the prime mover and the working machine, used to reduce speed and increase torque.

What are the characteristics of gear reducers?

Gears are made of high-strength low-carbon alloy steel through carburizing and quenching treatment, achieving high hardness and wear resistance.

How does a planetary gearbox work?

A ring gear is fixed to the housing, a sun gear is driven by the input shaft, and planet gears rotate around it, delivering high torque through the carrier.

Do you offer custom gearbox solutions?

Yes, we have a strong R&D team and can develop and produce products according to customer drawings or samples.

What certifications do you hold?

We are certified with ISO 9001, CE, ROHS, CQ, IP, and AAA credit rating, ensuring quality and compliance.
