Your advantages

High flexibility
is offered by the servo gear unit in direct motor mounting, as the usual adapter with clamp coupling is no longer required.

Enormous performance
thanks to high operating speeds and efficiencies.

Great reliability
thanks to wear-free gearing and consistently low rotational clearance.

Helical-bevel servo gear unit series BS.F

Low backlash servo planetary gear units - convincingly conveyed!

High rotational speeds and high torques combined with precision and cost-effectiveness: our compact planetary servo gear units in two series offer you countless possible solutions combined with a variety of motor mounting options via the EPH motor adapter for PS.F and ECH for PS.C.

In connection with consistently low rotational clearances, high torsional stiffness and high economic efficiency, these high-precision and very powerful servo gear units form the optimum basis for a wide range of servo drives.

The servo planetary gearboxes are designed planetary gear units of the PS.F series are designed for nominal torques from 25 Nm to 3000 Nm, the PS.C series for nominal torques from 30 Nm to 320 Nm.

All gear ratios from i = 3 to i = 100 are integer and finely stepped. This makes the servo gear units particularly suitable for use on open-loop controls where integer resolution ratios are required.

Only half the solution without a motor? Then use our modular system and combine the servo gear units from the PS.F and PS.C series with a dynamic servomotor of your choice.
