Festo DGP-50-PPV-A-B-9M Rodless Pneumatic Cylinder — 50 mm Bore, 9 m Stroke with Seal Strip Service Pack

FESTO · DGP Series · Rodless Cylinder · Service Pack · In stock

The Festo DGP-50-PPV-A-B-9M is a standard-profile rodless pneumatic cylinder from Festo's DGP family, with a 50 mm bore, 9 000 mm (9 m) stroke, integrated PPV pneumatic cushioning at both end positions, a magnetic A piston for position-sensor mounting, and the basic B version package. The listing ships with the matching seal / strip service pack so you can rebuild the cylinder in the field without sending the entire actuator out for service.

The DGP-50-PPV-A-B-9M is a long-stroke workhorse: it is selected whenever a conventional rod cylinder would be too long for the envelope, or when a moving carriage has to share the same axis as the cylinder body — typical in factory automation transfer lines, packaging machinery, and CNC loading / unloading cells. Festo is a reference name in industrial pneumatics; KOEED keeps this exact bore / stroke in stock alongside the full DGP bore range and ships worldwide.

1. Key Technical Specifications & Overview

The DGP-50-PPV-A-B-9M follows Festo's standard-profile DGP naming convention: DGP = standard-profile rodless cylinder, 50 = 50 mm piston diameter, PPV = integrated pneumatic end-position cushioning (adjustable on both ends), A = magnetic piston (compatible with Festo position sensors), B = basic version (the standard package, no external options bundled), and 9M = 9 000 mm (9 m) stroke length. This listing is shipped as the seal strip / band service pack — the consumable wear parts you need to rebuild an existing DGP-50 cylinder during scheduled maintenance.

2. Application Scenarios — Where the DGP-50-PPV-A-B-9M Fits

Rodless cylinders are the right answer whenever a normal rod cylinder would be too long for the available envelope, or when a moving load has to ride on the same axis as the cylinder body. The 9 m stroke of the DGP-50-PPV-A-B-9M is what you reach for in long horizontal transfer sections where a rod cylinder simply will not fit.

• Long-stroke transfer conveyors — moving pallets, totes, or trays between workstations in factory automation lines.
• Packaging and bottling machinery — horizontal carriage drives for Allen-Bradley-controlled packaging cells and Siemens SIMATIC packaging skids.
• CNC loading / unloading cells — shuttle motion for raw stock and finished parts feeding Fanuc / Mitsubishi machining centers.
• Pick-and-place gantries — horizontal axis where the moving gripper must stay compact while the load travels long distances.
• Printing and labelling lines — long travel of print heads, applicators, or web-tracking carriages.
• Wood, glass, and metal cutting tables — moving the cutting head along the workpiece when a 9 m reach is needed.
• Automotive body-in-white and assembly cells — integrated into Omron / Yaskawa / Schneider controlled sub-assemblies.
• Vision inspection stations — carrying parts past KEYENCE or Panasonic vision systems for full-length scanning.
• Maintenance rebuild of an existing DGP-50 — this listing is the service pack, so it is also the part you stock to keep your installed fleet alive during scheduled shutdowns.

3. Integration & Wiring Notes

The DGP-50 is a purely pneumatic actuator — there is no electrical port on the cylinder itself — but the A magnetic piston opens up the option of fitting Festo position sensors (typically SME-8 / SMT-8 type) into the two sensor slots on the DGP-50-PPV-A-B body. That means the cylinder talks to your control system through standard 24 V DC discrete inputs, not a fieldbus port.

• Pneumatic ports — 9 m DGP-50 cylinders typically use G1/4 (or NPT1/4 on NA-spec builds) on both end caps. Tee into a 5/2 or 5/3 solenoid valve (Festo VUVG, Siemens Sirio, or equivalent) for double-solenoid control, or a single-solenoid spring-return valve for simple extend / retract.
• Sensor wiring — mount two Festo magnetic proximity sensors in the body slots, run PNP-style 3-wire cabling back to your PLC digital input module (e.g. Allen-Bradley 1734-IB8, Siemens SM 1221, Mitsubishi QX42, or Omron CP1W-8ED).
• Controller pairings — any of the nine KOEED brands can sequence the cylinder: Allen-Bradley CompactLogix / ControlLogix, Siemens S7-1200 / S7-1500, Mitsubishi MELSEC iQ-R, Omron CJ2 / NX, Fanuc PMC, Schneider Modicon M340, Yaskawa MP2300, Panasonic FP-X, or KEYENCE KV series.
• Cushioning setup — the PPV pneumatic cushioning must be tuned at commissioning. Close the needle valve fully, then back off 1–2 turns and run the load at production speed. Adjust so the carriage decelerates smoothly without bottoming out.
• Air quality — use a Festo MSB4 / MS6 service unit (filter + regulator + lubricator) upstream. ISO 8573-1:2010 class 7:4:2 or better keeps the seal strip service intervals realistic.
• Service pack swap — when you swap the included seal strip / band service pack, the cylinder does not need to leave the machine. De-pressurize, lock out the air, slide the carriage off, replace the band and the wipers, re-grease, and the DGP-50 is back in service.

4. Installation & Commissioning Tips

A 9 m rodless cylinder is unforgiving of poor installation — any twist in the body shows up as seal wear within weeks. Walk through the points below before powering up the line.

• Support the body every 1–1.5 m. The DGP-50 is a long, rigid extrusion. Use Festo foot-mounting kits or mid-section supports so the body does not sag under its own weight, and so the carriage seals do not take the load.
• Level the body on the mounting surface. Misalignment of more than 0.5 mm/m will accelerate the seal strip. Shimming under each support is normal practice.
• Keep the strip area clean. The metal carrier band and the seal slot on a DGP-50 are sensitive to weld spatter, swarf, and dust. Cap the strip slot during any nearby welding or grinding work.
• First-run cushioning tune. Start with the PPV needle valves fully closed, run a slow cycle to confirm the end cushions engage, then open each needle 1–2 turns. Listen for the soft “thud” of cushioning — a hard impact means you need more cushioning.
• Lubricate the seal strip on assembly. When fitting the seal strip service pack, apply the Festo-recommended grease to the seal lips and the carrier band. Dry assembly is the fastest way to kill a fresh seal kit.
• Sensor placement. Mount the Festo proximity sensors so they detect the magnetic piston at the intended end-of-stroke position, not mid-stroke. Confirm detection by jogging slowly with the PLC in manual mode.
• Schedule seal-strip service. A DGP-50 in a 3-shift packaging line typically needs the seal strip refreshed every 12–18 months. Stock the DGP-50-PPV-A-B-9M service pack as a planned-maintenance item rather than waiting for a leak.
• Watch the load. The 50 mm bore at 6 bar gives roughly 1.2 kN of theoretical thrust. Stay well below this with a 2–3× safety margin for horizontal transfer duty; vertical lift duty needs a separate lock-valve and a margin larger still.
