Guided actuator for precision motion

The Festo DFM-20-25-P-A-GF is a guided actuator designed for controlled linear movement in automation tasks. It integrates a cylinder with a built-in guide mechanism to resist side loads and maintain alignment. Supplied new in a single pack under part number 170841, it suits machine builders who need repeatable positioning.

Automation engineers needing anti-rotation guidance

This unit fits engineers who require a ready-to-mount actuator with internal plain-bearing guide rods to prevent piston rotation. It is not suited for applications demanding external guide rails, high-speed pneumatic cycles beyond the unit's design, or environments where the red finish indicates an incompatible specification.

20 mm bore with 25 mm stroke defines fit

The 20 mm bore and 25 mm stroke set the force output and travel distance available for the application. Verify these dimensions against the mechanical layout before ordering, as they determine whether the actuator can deliver the required push or pull within the available space.

Questions about this item

Should I choose the 20 mm bore or the 25 mm stroke version of the DFM-20-25-P-A-GF?

The model DFM-20-25-P-A-GF has a 20 mm bore and a 25 mm stroke; both figures are fixed in this part number so you do not select between them.

What does the 25 mm stroke deliver in a real installation?

The 25 mm stroke gives 25 mm of linear travel for the guided piston, suited to short positioning tasks in fixture or assembly setups.

Which pneumatic interface does the DFM-20-25-P-A-GF use and what does it limit?

It uses standard pneumatic ports for compressed air supply; the 20 mm bore and 25 mm stroke define the force and travel limits in practice.
