Festo DFM Series Pneumatic Guided Cylinder, 25mm Bore Size, 40mm Stroke Length - DFM-25-40-P-A-GF

This pneumatic guided cylinder is a compact guided actuator designed to deliver controlled linear motion in industrial pneumatic systems. It operates as a double-acting cylinder with guided support to reduce lateral load on the piston rod, suitable for confined installations where guided, repeatable strokes are required. The unit is built for operation across a broad temperature span and is compatible with common pneumatic installations requiring standardised rod thread interfaces.

Features and Benefits:

• 25mm bore with 40mm stroke provides compact linear motion
• Double-acting configuration enables active extension and retraction
• Maximum operating pressure 10 bar supports robust pneumatic force
• Maximum piston speed 0.8 m/s allows predictable cycle timing
• Plain bearing guide reduces wear under side loads
• Elastic cushioning rings and plates deliver smooth deceleration

Applications

• Suitable for pick-and-place in compact automation cells
• Ideal for small transfer and positioning tasks
• Used in stainless environments requiring corrosion resistance
• Can be used for guided clamping in assembly fixtures
• Appropriate for machinery requiring standardised rod threads

What materials make the unit suitable for corrosive environments?

The guided cylinder uses high-alloy stainless steel alongside tempered steel and wrought aluminium alloy components to enhance resistance to corrosive atmospheres while maintaining structural strength.

How is sealing and wear addressed in the design?

Sealing elements are made from nitrile rubber and polyurethane to provide durable sealing against compressed air and to reduce friction at dynamic interfaces.

What mounting options are available for installation flexibility?

It offers through-hole, flat and side mounting configurations to accommodate a variety of fixture orientations and space constraints.

How does the product manage temperature extremes during operation?

It is rated to operate down to -20°C and up to 80°C, allowing deployment in cold-storage handling or elevated-temperature production areas.
