Festo
3656644
ISO cylinder DSBC-80-250-D3-PPVA-N3
The Festo 3656644 is a double-acting industrial component featuring an 80 mm piston diameter, a 250 mm stroke, and an M20x1.5 external piston rod thread conforming to ISO 15552. Constructed with a piston, piston rod, and profile barrel design, it incorporates adjustable pneumatic cushioning at both ends with a 31 mm cushioning length and 1.8 J impact energy capacity. Operating within a pressure range of 0.04 MPa to 1.2 MPa and an ambient temperature range of -20 °C to 80 °C, this unit delivers a theoretical retracting force of 2721 N at 6 bar using compressed air meeting ISO 8573-1:2010 [7:4:4].

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.
