Guided Actuator for Linear Motion

The Festo DFM-25-40-P-A-GF 170850 is a guided actuator designed to provide precise linear movement with integrated guidance. It is built for automation tasks where controlled motion and load-bearing capacity are required. The unit is supplied new in a single pack box with a red finish. This component suits engineers assembling pick-and-place or material-handling systems.

Suited for Guided Stroke Applications

This actuator fits builders who need a ready-to-mount guided drive with a 25 mm bore and 40 mm stroke for standard automation sequences. It is not for buyers who need a different bore diameter, a longer or shorter stroke length, or a non-guided rodless cylinder variant. The fixed specification means the part cannot be adapted to alternative travel or force requirements.

Bore and Stroke Define Fit

The 25 mm bore and 40 mm stroke are the primary dimensions that determine whether this actuator matches the mechanical design. Verify these two values against your machine layout before ordering. No other specification in the data overrides this mechanical compatibility check.

Questions about this item

Should I choose the DFM-25-40-P-A-GF model or a different capacity for my application?

The DFM-25-40-P-A-GF is a single guided actuator with a 25 mm bore and 40 mm stroke; select it when those exact dimensions match your machine design, otherwise choose a variant with the required bore and stroke.

What does the 40 mm stroke mean once the actuator is installed in a real machine?

The 40 mm stroke defines the maximum linear travel the guided carriage can achieve between its end positions, so the machine layout must provide at least that much clear space for the full working movement.

Which pneumatic interface does the DFM-25-40-P-A-GF use and what does it cap in practice?

The actuator connects via standard pneumatic ports sized for the 25 mm bore, so the practical flow and pressure limits are those of the supply tubing and valve package you install with it.
