Our 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 our ATEX-compliant planetary servo gear units apart.
Our 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.
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.
Only half the solution without a motor? Then use our sophisticated modular concept and combine the explosion-proof servo gear units of the PS.F series with the explosion-proof servomotor of your choice.
