The precision gearboxes from Melior Motion are effectively backlash-free, with a backlash of ≤ 0.1 arcmin and a lost motion of ≤0.6 arcmin they offer maximum precision and accuracy even in the low torque range.

The patented wear control self-regulating gearing system, ensures that the circumferential backlash does not change over the entire service life and that constant precision is maintained.

The low-backlash PSC precision gears achieve a particularly high-power density thanks to multiple tooth meshing (sun gear, planetary gears and ring gear). The efficiency of > 90% and the extremely low breakaway torque ensure outstanding energy efficiency and controllability.

Due to high output, acceleration and emergency stop torque ratings, the precision gearboxes provide more safety for the application. An enormous tilting and torsional rigidity enables precise positioning. Low vibrations of the precision gears ensure high path accuracy.

The lower weight and the compact design enable a lighter overall system and a smart surrounding construction.

The service life is an impressive 20,000 hours. The temperature in the gearbox remains constant at a particularly low level, which means that oilseals and lubrication are subject to significantly less stress, resulting in much longer operational life.

The PSC series is available in seven sizes as sub-assemblies or fully enclosed gearboxes. The mounting kits and gear blocks of the PSC series are available as solid shaft or hollow shaft versions. The hollow shaft design offers the advantage that data or supply lines can be routed through the hollow shaft with a diameter of up to 75 mm.

Sub-assemblies PSC-V/H-E

The sub-assemblies of the PSC series are particularly low-backlash and offer maximum accuracy even in the range of low torques. The mounting kits can be mounted directly in the drive. They are used in robotics and automation.

Fully enclosed gearboxes PSC-V/H-B

The transmission blocks of the PSC series are filled with standard mineral-based oil as standard. Thanks to various interfaces, they can be easily adapted to the most common servo motors. They are used in many applications, including robotics, automation, machine tools, printing, rotary tables and medical technology.
