The combination of a worm gear and a helical gear stage, or another worm gear, as a so-called double worm gear drive version increases the efficiency rate as is the case in pure worm-geared drive. These helical worm gear units run very smoothly and almost noise free, due to their linear force transmission. As a compact drive unit with our motors they can be used in a variety of ways.
The worm gear drives can be used as ATEX version with a corrosion protected surface, with food grade oil and other further options.
