• The main components are designed and manufactured in a modular and serialized manner.
• Adopting first, second or third gear reduction, the input shaft and output shaft are basically coaxial.
• It is equipped with standard or non-standard motor interfaces and supports foot mounting, flange mounting and shaft mounting forms.
• The gears are made of high-quality low-carbon alloy steel with carburizing, quenching and gear grinding processes, featuring more reliable operation, high transmission accuracy and low operating noise.
