Festo Pneumatic Guided Cylinder 40 mm Bore, DFM Series, 25 mm Stroke, Double Acting, Elastomer Cushioning DFM-40-25-P-A-GF

Festo DFM-40-25-P-A-GF pneumatic guided cylinder is a robust and precise actuator designed for demanding pneumatic applications in industrial, manufacturing, and automation settings. This double acting guided cylinder with a 40 mm bore diameter and 25 mm stroke integrates both drive and sliding guide elements into a compact, maintenance-free aluminium housing, ensuring high resistance to torque and lateral forces encountered during heavy duty operations.

The unit features four plain slide bearings on large diameter guide rods that provide exceptional rigidity and smooth motion, making it suitable for applications requiring reliable clamping, stopping, lifting, and material handling. Elastomer cushioning plates are incorporated to reduce noise and enhance operational lifespan, promoting quieter and longer service deployments.

With flexible air supply ports mounted both on top and side of the cylinder, the installation geometry can be adapted to specific machine and process layouts. The cylinder is designed with integrated slots to allow proximity sensors, facilitating precise measurement of piston linear motion for enhanced control.

The model adheres to key industry standards including RoHS compliance and ISO 228-1 and ISO 1179-1 certifications, ensuring compatibility and quality assurance. Operating pressure is rated up to 10 bar with a temperature range from -20°C minimum to 80°C maximum, suitable for a broad array of industrial environments including mechanical, fluid power, and automation sectors.

Typical applications include use as a guided drive for clamping operations, a stopper for loads up to 150 kg, and a powerful lifter for dynamic material handling tasks. The compact aluminium design balances durability with light weight, facilitating installation and integration into diverse pneumatic systems.

Combines drive and guide function into one housing for high rigidity and performance. Four slide bearings provide excellent lateral force resistance and smooth operation. Flexible mounting with air ports on multiple faces enhances installation versatility.
