• Beautiful appearance and stable design
• Optimization design of each part including the case has improved structure strength and lifetime
• Production of motor flange type or motor attached type has improved user convenience

worm reduction gear has wide range of choice for Power (0.2kW~75kW) and reduction gear ratio (1/10~1/3600),
and having diverse product types including Up Type, Bottom Type, Vertical Type and 2 Stage Type, it can satisfy diverse customer requirements.worm gearboxes offer users a high torque output multiplier and are able to withstand shock loading better than other designs. Worm gear reducers are also low cost and compact.Worm gearboxes are used to take a rated motor speed and produce a low-speed, high torque output based on the reduction ratio, offering users a number of advantages.
Worm gear set advantages:

• Easy and functional shaft mounting
• Noiselessness, constant performance, also for the heaviest applications
• High performance and reliability
• Lower power consumption
• Long life

Powerful and highly efficient high-grade worm reducer


We are a factory specialized in metal parts hardware & metal gearbox geared motor .We services with ODM/OEM gearbox design and development , gearmotors manufacture.
A  gearbox is  with the input shaft and output shaft aligned it offers high torque transmission with good stiffness and low noise , in a more compact foot print than other gearbox types . It can supply a lot of speed reduction and torque in a small package with the fixed axis .Gearbox is ensure that it provides highly accurate gear engagement, smooth running and minimum noise and give the ability to increase the torque and lower the speed of an electric motor.
