Frequently Asked Questions - DPDM-25-25-PA Festo
What is the operating pressure range of the Festo DPDM-25-25-PA?
The operating pressure ranges from 1.5 to 10 bar. Ensure the supply does not exceed the maximum to avoid damage.
Can I use oil in the air supply for this cylinder?
The cylinder is designed for lubricated or unlubricated operation. However, if lubricated, continuous lubrication is required. Use oils compatible with NBR seals.
What size are the mounting threads?
The cylinder has M5 ports for air connections and M6 piston rod thread. Mounting holes are through-hole for M4 screws.
How do I adjust the cushioning?
The self-adjusting cushioning (PPS) adapts automatically. No manual adjustment is needed. For special cases, check the end caps for optional screw adjustments.
Is the cylinder suitable for outdoor use?
It has KBK class 2 corrosion resistance, which is moderate. For outdoor use, protect from direct moisture and apply additional coatings if necessary.
What is the maximum ambient temperature?
The allowed ambient and fluid temperature range is -20 to 80 °C. Avoid temperatures below -20°C to prevent seal hardening.
Can I mount this cylinder vertically?
Yes, vertical mounting is possible. Ensure the load is properly guided and the mounting screws are tightened to the specified torque (36 Nm for M4).
How do I replace the seals?
Use the official seal kit (part number: DPDM-25-PA-SK). Disassemble the cylinder carefully, clean the grooves, and install new seals. Refer to the manual for disassembly instructions.
What is the stroke tolerance?
The stroke length tolerance is ±1 mm under no load conditions. For exact positioning, use external sensors and control systems.
Does it have position sensing capability?
Yes, the cylinder has an integrated T-slot for mounting proximity sensors (e.g., Festo SME/SMT series). The sensors detect the piston position for end-of-stroke signaling.
