Guided actuator for precision motion

The Festo DFM-20-40-P-A-KF 170918 is a guided actuator built for controlled linear movement in automated systems. It suits engineers and integrators who need repeatable positioning in assembly or handling tasks. The unit arrives new in a single pack with a red finish. It is not intended for applications requiring rotary motion or untracked free travel.

Thermals noise and power profile

The actuator operates on compressed air rather than electrical power, so it produces no electrical heat or motor noise during normal cycling. Energy consumption depends entirely on the supply pressure and cycle rate set by the pneumatic circuit. There are no onboard fans, heat sinks or power electronics to manage. Buyers needing an electrically driven alternative will not find that capability here.

Included accessories and software impact

The box contains one guided actuator unit identified by model number DFM-20-40-P-A-KF and part reference 170918. No mounting brackets, sensors, tubing or configuration software are bundled with this pack. Spare parts coverage extends for three years while labour coverage lasts one year. Users must source fittings and control components separately to complete the installation.

Questions about this item

How is the DFM-20-40-P-A-KF guided actuator mounted and what alignment step is critical?

Mount the unit using the four through-holes on the body; the step often missed is aligning the guide rods parallel to the load path before tightening, otherwise the plain-bearing bushes bind.

Which wear items on the DFM-20-40-P-A-KF will need replacement after extended cycles?

The plain-bearing guide bushes and the piston rod seals are the primary wear parts; plan to inspect them at the major service interval.

What mechanical limit appears first on the DFM-20-40-P-A-KF during continuous high-speed cycling?

The cushioning stroke at the end positions reaches its absorption limit first, causing metal-to-metal contact if the kinetic energy exceeds the built-in cushion capacity.
