Frequently Asked Questions - DFM-25-30-B-PPV-A-KF Festo
What is the Festo DFM-25-30-B-PPV-A-KF?
It is a guided pneumatic cylinder (linear drive) with a 25 mm piston diameter and 30 mm stroke. It is used for precise linear motion in automation systems.
What are the main technical specifications?
Key specifications include a 25 mm piston diameter, 30 mm stroke length, adjustable end-position cushioning (PPV), and an operating pressure range of approximately 1 to 10 bar.
How do I connect compressed air to this cylinder?
Use the air ports located on the cylinder body. Typically the ports are G 1/8 or similar. Connect via suitable fittings and ensure the pressure is within the rated range.
Can the stroke be adjusted externally?
No, the stroke is fixed at 30 mm for this model. For adjustable strokes, consider a different cylinder type or separate limit switches.
How do I adjust the cushioning (PPV)?
The PPV cushioning has two screws at each end. Turn clockwise to increase damping and counterclockwise to reduce it. Adjust while running the cylinder at low speed until end-position impact is damped.
What maintenance does this cylinder require?
Perform periodic visual inspection for damage or leaks. Clean the guide rods and exterior with a soft cloth. No external lubrication is needed if the compressed air is clean and dry.
Are spare parts available for this model?
Yes, Festo offers seal kits, wiper seals, and guide components. Use the model number to find the appropriate spare parts catalog or contact Festo support.
What is the maximum load this cylinder can handle?
The load capacity depends on the operating pressure, stroke, and mounting orientation. At 6 bar, the theoretical force is about 290 N for a 25 mm bore, but dynamic loads should be checked with the datasheet.
Can I mount the cylinder vertically or horizontally?
Yes, the DFM series can be mounted in any position. For vertical mounting above a certain load, consider a counterbalance or travel guide to prevent overloading the guides.
What does the suffix 'KF' mean in the model number?
The 'KF' suffix typically indicates a specific option or configuration, such as an extended guide or special seals. For exact details, refer to the Festo datasheet or contact their technical support.
