Guided actuator for precision motion

The Festo DFM-40-50-P-A-GF is a guided actuator designed for controlled linear movement in automated systems. It integrates a 40 mm bore and 50 mm stroke within a single unit. The red finished body houses internal guide rods that resist side loads and maintain alignment. This new unit arrives as one pack in a box.

Suited for fixed-stroke automation tasks

Engineers building pick-and-place, clamping or pressing stations with a 50 mm travel requirement will find the dimensions match. The integrated guide removes the need for separate linear bearings. Buyers who need adjustable stroke lengths or longer travel should look at other actuator families. Applications requiring higher speed or different mounting patterns are not addressed by this model.

50 mm stroke defines the working range

The 50 mm stroke is the fixed linear travel this actuator delivers. It determines whether the part fits the mechanical cycle of the machine being built. No other stroke option exists for this specific model number 170865. Verify the required travel before ordering.

Questions about this item

What comes in the box with the DFM-40-50-P-A-GF and what must be purchased separately?

The box contains one guided actuator unit. Mounting hardware, tubing, fittings and position sensors are not included and must be sourced separately.

How do I choose between the DFM-40-50-P-A-GF and other DFM variants?

This model has a 40 mm bore and 50 mm stroke. Select it when those dimensions match your application; other variants use different bore or stroke values.

What does the 50 mm stroke mean when the actuator is installed in a machine?

It provides 50 mm of linear travel for the guided carriage, allowing precise positioning of tooling or workpieces over that distance.
