Festo
4840838
Compact cylinder DPDM-Q-25-5-P-PA
The Festo 4840838 is a single-acting, pulling industrial component featuring a 25 mm piston diameter, a 5 mm stroke, and a piston rod at one end with a guide rod and yoke for torsion protection. Operating on compressed air within a 0.15 MPa to 0.8 MPa pressure range, this unit utilizes elastic cushioning rings at both ends and provides a theoretical force of 221 N retracting and advancing at 6 bar. Position sensing is achieved via proximity switch, and the assembly is rated for a moderate corrosion resistance class of 2 across an ambient temperature range of -10 °C to 80 °C.

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.
