Festo
4829573
Compact cylinder DPDM-25-20-PA
The Festo part number 4829573 is a double-acting industrial component featuring a 25 mm piston diameter and a 20 mm stroke with a piston rod at one end. Operating on compressed air within a 1 bar to 8 bar pressure range, this piston barrel design delivers a theoretical advancing force of 295 N and a retracting force of 247 N at 6 bar. It incorporates elastic cushioning rings at both ends, position sensing via proximity switch, and offers Class 6 cleanroom suitability according to ISO 14644-1 with moderate corrosion resistance class 2.

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.
