Festo
1646779
ISO cylinder DSBG-80-250-PPVA-N3
The Festo 1646779 is an ISO 15552 compliant double-acting industrial component featuring an 80 mm piston diameter, a 250 mm stroke, and an M20x1.5 external piston rod thread. Designed with a tie rod structural configuration for operation within a 0.04 MPa to 1.2 MPa pressure range, this unit includes adjustable pneumatic cushioning at both ends and position sensing via proximity switch. It operates on compressed air conforming to ISO 8573-1:2010 [7:4:4] within an ambient temperature range of -20 °C to 80 °C and achieves a theoretical retracting force of 2721 N at 6 bar.

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.
