Why Choose a Planetdrive Servo Gearhead?

There are many more servo controlled applications requiring general torque transmission and speed reduction than there are needing highly dynamic operation and super precision.

While cost expectations for the gearheads used in these general purpose designs are lower, the need for reliability is still high. That's where the Planetdrive is most appropriate.

A result of German engineering and including many design features found in more expensive gearheads, the Planetdrive provides high quality and excellent performance at an economical price. With that kind of value, why would you choose another brand?
