Your benefits

Space-saving installation
thanks to custom coordination options for torque and speed in all seven sizes.

High efficiency
thanks to the simple design of the helical-worm gear unit.

Low-noise operation
because the linear power transmission attenuates torque impulses on the drive shaft.

K series helical-bevel gear units W series SPIROPLAN® right-angle gear units
S series helical-worm gear units – simple design, exceptionally smooth-running

While their cost-effectiveness is due to their simple design, custom coordination options for torque and speed ensure our helical-worm gear units are compact for ease of installation. Use S series helical-worm gear units as a cost-effective solution for meeting basic requirements in your machine or plant applications.

Adding in a helical gear stage means that significantly higher efficiency can be achieved than when using plain worm gear units. The linear power transmission makes these helical-worm gear units exceptionally smooth-running and low-noise. Why? Power is transmitted to the input shaft via the worm shaft and worm gear in a process that reduces torque impulses and facilitates low noise levels.

The torque range extends from 92 to 4000 Nm. For the new S..7p it is 105 Nm to 4300 Nm.
