S serie helical worm gearbox adopts the helical gear-worm wheel type to make the structure more reasonable. S series helical worm gearbox not only has higher transmission efficiency and loading capability than those of single-stage worm wheel transmission, but also reduces space. Moreover, under the close volume.

S series helical worm gearbox can obtain higher transmission ratio and is more favorable for equipment setting. The product can be combined with various reducers and variators to meet the different requirements.
