Festo
4840840
Compact cylinder DPDM-Q-25-15-P-PA
The Festo 4840840 is a single-acting industrial component featuring a 25 mm piston diameter, a 15 mm stroke, and a pulling mode of operation with elastic cushioning rings at both ends. Designed with a piston rod at one end and a guide rod with a yoke providing protection against torsion, this profile barrel assembly operates on compressed air from 1.5 to 8 bar within an ambient temperature range of -10 °C to 80 °C. It achieves a theoretical retracting and advancing force of 221 N at 6 bar, incorporates position sensing via proximity switch, and meets ISO 14644-1 Class 6 cleanroom suitability with a CRC 2 moderate corrosion resistance rating.

Request a QuoteWhy no listed price?
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
