Festo DFM-100-125-P-A-GF 170896 guided actuator

Guided actuator for precision motion

The Festo DFM-100-125-P-A-GF is a guided actuator built for controlled linear movement in automation tasks. It suits engineers and technicians who need repeatable positioning in machine building or process equipment. The unit arrives new and ready for integration into existing pneumatic or electric systems. Its compact guide design helps maintain alignment under load.

Stroke and bore define the working envelope

With a 100 millimetre bore and a 125 millimetre stroke the actuator delivers a defined travel range for medium-force applications. It handles moderate side loads and moments without external guide rails, reducing assembly complexity. The stroke length sets a hard limit on single-move distance, so longer traverses require a different model or mechanical extension. Force output scales with supply pressure and bore area.

Mounting pattern and port locations drive layout

The actuator uses Festo standard mounting holes and pneumatic ports, so it fits established manifold plates and valve islands without adapters. Its guided piston rod eliminates the need for separate linear bearings in many designs, freeing space and cutting part count. Alignment is maintained by the internal plain-bearing guide, which also resists rotation. Ensure the supply pressure and control logic match the cylinder’s pressure rating and sensor options.
