S Series Helical Worm Gear Motor

Short Description:

Product description:

S series helical worm gear motor using both advantages from helical and worm gears. The combination offers high ratios with increased efficiency, keeping the high load carrying capacity of a worm gear unit.


The Series S range is a top quality design and uses high quality materials and components. It is also manufactured and assembled using our modular swift kit units for minimizing inventory and increasing availability.


These modular gearboxes can be used with hollow shaft and torque arm but also come with outputshaft and feet. The motors are mounted with IEC standard flanges and allow easy maintenance. Gear cases are in cast iron.




1.High modular design, biomimetic surface with owned intellectual property right.

2.Adopt German worm hob to process the worm wheel.

3.With the special gear geometry, it gets high torque, efficiency and long life circle.

4.Can achieve the direct combination for two sets of gearbox.

5.Mounting mode: foot mounted, flange mounted, torque arm mounted.

6.Output shaft: solid shaft, hollow shaft.


Main applied for:


1.Chemical industry and environmental protection

2.Metal processing

3.Building and construction

4.Agriculture and food

5.Textile and leather

6.Forest and paper

7.Car washing machinery
