Helical Gear Speed Reducer






  • According to German Institute for Standardization (DIN) design-high efficiency, high strength, and low noise.
  • Complete specifications come out diverse installations.
  • Cast iron made housing strengthen the crash-against.
  • In order to improve the intensity and service life of gear reducer, the speed ration of 30:1 ~ 120:1 are designed as three stages gear sets, and the speed ratio 5:1 ~ 25:1 have two stages and three stages at your choice.
  • Differing from only one bearing support, our two bearings support input pinion come out steady rotation.
  • Motor’s shaft insert design on input flange made easily to install IEC or NEMA motor.
  • Wide range ration from 5:1 ~ 120:1.
  • Horsepower range from 1/4HP to 78HP.
  • Gear parts with precise procession make gears rotation even quieter and more efficient.
  • Installation and shaft dimensions are compatible with German Brand..
  • Beautify the appearance and lighten the weight.
  • One year limited warranty.


Helical+Worm Gear Speed Reducer






  • Design conception: combination of standardization and modularization to be compatible with international leading brands. With characteristic of rigid structure and compact body.
  • Low noise: gathering the advantage of helical gear high efficiency and worm gear smooth transmission, the transmission is more stable and less noise compare with standard helical gear speed reducer.
  • More ratios choice: the ratio range is between 8:1 ~ 210:1 which overcome the small ratio range issue of worm gear speed reducer.
  • Loading range: it can be freely chosen from 1/4HP up to 30HP according to different requirements and application.
  • Better strength: pinion, gear and worm shaft are 20CrMo alloy steel with carbonized treatment. And, the worm wheel is aluminum bronze which offers better strength and endurance.
  • Self-lock: in certain condition, it’s not reversible from output shaft (self-lock) makes transmission movement be safer.
  • Convenient for mounting: every models are suitable for any mounting position (M1~M6) as per different application. It’s easier and also more convenient.
  • Nice appearance with strong structure.
  • One year limited warranty.



Hollow Shaft Speed Reducer







  • Elegant appearance by powder coated on housing prevents from rusting. The mounting dimension is compatible with Italian gearboxes.
  • Aluminum alloy die-cast gearbox with light weight advantage.
  • Highly accuracy.
  • Forward and backward transmitting available.
  • Stable transmission with reduced vibration and noise.
  • Various optional accessories with easy installation.
  • Weight reduced design, can install right upon the equipment without trouble.
  • Enlarge radiated area for heat and increase durability.
  • Universal installation design, suitable for all different application of position.
  • High strength Hollow Output Shaft, higher loading duty than cast iron shaft.
  • Cr-Mo Alloy Steel Input Shaft with carburized treatment and teeth polished. Extremely strengthens the structure.
  • One year limited warranty.
