Helical-worm gear units

Optimised solutions for complexe motion cycles

To achieve higher transmission ranges and low-noise operation, the worm gear units can be combined with a helical gear unit. The first stage is made of standardised helical gears. High efficiency and torques allow for a compact drive design and reduce both space requirements and cost. Helical worm gear units are used for lifting and lowering loads and holding them safely in defined positions. To ensure optimum sizing for the machines and systems of our customers, GFC gear units are available in different sizes.
