Worm Motors

SA series is the type of hollow shaft mounted. For the SA series helical worm gearbox, the same type can be equipped with motors of various rate powers, and it is easy to realize the combination through the connection of various models. It has high transmission efficiency, and the efficiency of the single-type reducer is as high as 96%. And the transmission ratio is finely divided and has a wide range. The combined model can form a larger transmission ratio and achieve a low output speed. SA series helical worm gearbox can be installed in various forms like foot, B5 flange, B14 flange, hollow shaft, or torsion arm.

SA series helical worm gearbox is designed and manufactured on the basis of the modular combination system. There are many motor combinations, installation forms, and structural schemes. The wide range of transmission ratios meets different working conditions of our customers.
