Servo Gearmotor PSF Series
PSF series.
The low backlash PSF planetary servo gear units are designed for the 25 to 3000 Nm (220 to 26500 lb-in) torque classes. The permitted acceleration torques are significantly higher than these values.
Available versions
- PSF: Solid shaft
- PSKF: Solid shaft with key
- PSBF: Flange block shaft in accordance with EN ISO 9409
