* Short-term peak load <1s Axial load on the output side 500 Nm Application worm gear 65: 1 - 1: 1 Worm wheels transmit the motive force at right angles via a sliding effect. The gearboxes are characterized by their low-noise operation and robustness. The worm gears can be used for high power transmissions in tight spaces.
