More information


Worm gearboxes of the SG series are characterized by a compact design and a wide range of gear ratios. Lower gear ratios offer high efficiency, while higher ratios provide the advantage of self-locking. They feature a right-angle output, making them ideal for applications where axial space is limited. Worm gearboxes operate very quietly, making them suitable for noise-sensitive applications such as door automation or medical technology.
