Planetary Gears GSN

Planetengetriebe GSN

The GSN economy line is the perfect match for applications where a backlash of 10 arcmin or better is required. Its helical gears ensure a minimum noise level and a smooth running. The full needle bearing allows for torques that beat the competition for units of the same size. The GSN line is used for various applications with regard to precision and efficiency.
