Guided actuator with 25 mm stroke

The Festo DFM-40-25-P-A-GF is a guided actuator designed for precise linear motion in automation tasks. It belongs to the electrician tools category and carries part number 170864. The unit is supplied new in a single pack with a red finish.

Suited for guided linear motion.

This actuator suits engineers who need a guided piston rod to resist side loads and maintain alignment during reciprocating movement. It is not intended for applications that require pure rotary actuation, uncontrolled linear travel without guidance, or higher stroke lengths than the 25 mm this model provides.

25 mm stroke length defines the working range

The 25 mm stroke is the key specification that determines whether this actuator fits the required travel distance in a given machine design. If the application demands a longer or shorter travel, a different variant must be selected.

Highlights

  • Precise 25 mm stroke for controlled positioning
  • 40 mm bore delivers strong linear force
  • Guided design prevents rotation under load
  • New condition ensures full factory performance

Questions about this item

What size mounting holes does the DFM-40-25-P-A-GF guided actuator require?

The unit is built on a 40 mm bore with a 25 mm stroke, so mounting holes must match that bore spacing for secure installation.

How do I correctly plumb the pneumatic ports on the DFM-40-25-P-A-GF during installation?

Connect clean, dry compressed air to the designated ports; the step often missed is verifying flow direction arrows before pressurising the 40 mm bore cylinder.

Which wear parts on the DFM-40-25-P-A-GF guided actuator will need replacement over time?

Guide bushes and piston seals are the primary wear items; plan to inspect them at regular intervals to maintain smooth 25 mm stroke operation.
