SPN worm-gears can be supplied as single-stage units, or with an input spur-gear reduction stage, for foot or flange mounting. The low-backlash worm-gear units are, among other applications, used in machine tools and packaging machines both in continuous and cyclical operation.

Optimum material combinations and specially adapted tooth geometries ensure exceptional quietness and very uniform rotation.

SPN worm-gears units are available with a choice of solid, of hollow output shafts, or with output shafts on both sides.
