They feature a consistently low rotational clearance and high torsional rigidity. All gear ratios from i = 3 to i = 100 are integers and finely stepped. This means that these explosion-proof servo gear units in equipment category II are also especially suitable for use with controllers that require integer resolution ratios.




  • Low-backlash ATEX-compliant planetary servo gear units
  • Designed for torque classes from 25 Nm to 3000 Nm
  • Available in two output variants:
    • PSF: B5 output, flange, smooth solid shaft (without key)
    • PSKF: B5 output, flange, solid shaft with key

Explosion-proof planetary servo gear units


The explosion-proof servo gear units provide precision, performance and reliability in potentially explosive atmospheres. They reliably transfer high speeds and torques while absorbing high overhung loads.


Explosion-proof, low-backlash planetary servo gear units: compact and reliable


Explosion protection with a compact design, high speeds and high torques: That’s what sets the ATEX-compliant planetary servo gear units apart.


The planetary gear units reliably deliver precision and cost-effectiveness in potentially explosive atmospheres. The PS.F series offers torques from 25 Nm to 3000 Nm.
