Festo
35191
ISO cylinder DSNU-25-400-P-A
The Festo 35191 is a double-acting industrial component featuring a 25 mm piston diameter, a 400 mm stroke, and an M10x1.25 external piston rod thread conforming to ISO 6432 and CETOP RP 52 P standards. Operating at pressures from 1 bar to 10 bar with compressed air, this unit incorporates elastic cushioning rings at both ends, position sensing via proximity switch, and moderate corrosion resistance class 2. It delivers a theoretical retracting force of 247.4 N at 6 bar across an ambient temperature range of -20 °C to 80 °C while meeting ISO 14644-1 cleanroom Class 6 suitability.

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.
