Planetary gearboxes


The low-backlash economy planetary gearboxes offer high performance and torque in a compact design. The one, two or three-stage gearboxes are available in five sizes for drive torques between 5 and 500 Nm. As a result of the high stiffness and overload capacity but at the same time low inertia, the PLZ gearboxes can be used in a very wide variety of applications.
