Lenze GKS helical-bevel gearboxes have the major benefit of enabling extremely precise and reproducible positioning movements due to their high torsional stiffness and low backlash. In connection with three-phase AC and servo motors, they form an extremely compact unit. They are available in a 3- and 4-stage design with a torque of up to 103014 in-lbs (11,639 Nm) and a ratio of up to i=1936.
