Guided actuator for precision motion

The Festo DFM-40-25-P-A-KF is a guided actuator built for controlled linear movement in automation tasks. It carries the manufacturer part number 170939 and arrives in a single pack with a red finish. The unit is supplied new and includes a three-year parts guarantee with one year of labour coverage.

Suited for guided linear automation

This actuator fits applications that require a guided rod to resist side loads and maintain alignment during travel. It is not intended for unguided rod styles, rotary motion, or environments that demand a different mounting pattern or stroke length than the 25 mm figure specified.

Stroke length 25 mm decides fit

The 25 mm stroke is the critical dimension that determines whether the actuator matches the machine cycle. Verify the required travel against this value before ordering, as no other stroke option is described for this part number.

Questions about this item

Should I pick the DFM-40-25-P-A-KF or a different size for my application?

The model number shows a 40 mm bore and 25 mm stroke; choose this version when those dimensions match your mounting and travel requirements.

What does the 25 mm stroke deliver in actual use?

It provides 25 mm of guided linear travel, letting the actuator move a load precisely over that distance in a machine.

Which pneumatic interface does the DFM-40-25-P-A-KF use and what does it limit?

It uses standard pneumatic ports; the 40 mm bore caps the maximum force at the available supply pressure.
