Guided actuator with plain bearing

The Festo DFM-20-50-P-A-GF is a guided actuator built for precise linear motion in automated systems. It combines a pneumatic cylinder with an integrated guide to handle side loads and prevent rotation. The unit is supplied new and ready for installation in machines that require repeatable positioning. Part number 170844 identifies this specific configuration.

Suited for guided linear tasks

This actuator fits applications where a load must move along a defined path without external guide rails. It is not intended for rotary actuation or for environments that require a different stroke length than the one this model provides. Buyers needing a different bore size or guide type should select an alternative variant.

20 mm bore with 50 mm stroke

The bore diameter is 20 mm and the stroke is 50 mm, which together define the force and travel available. These two dimensions determine whether the actuator matches the mechanical requirements of the application. Confirm both values against the design specification before ordering.

Questions about this item

What interface standard does the DFM-20-50-P-A-GF guided actuator use for pneumatic connection?

The DFM-20-50-P-A-GF guided actuator uses standard pneumatic port interfaces for compressed air supply, with the 20 indicating the bore size in millimetres that determines the flow capacity.

What are the physical mounting dimensions and stroke length for the DFM-20-50-P-A-GF guided actuator?

The DFM-20-50-P-A-GF has a 20 mm bore and 50 mm stroke length, with mounting holes patterned for the guided actuator body to secure it to machine frames or fixtures.

How is the DFM-20-50-P-A-GF guided actuator installed, and what is the common mistake to avoid?

Mount the actuator body securely using the through-holes, then connect pneumatic tubing to the ports; the common mistake is applying side loads to the guide rods before pressurising the cylinder.
