Festo
1779442
ISO cylinder DSBF-C-40-500-PPSA-N3-R
The Festo 1779442 is a double-acting industrial component featuring a 40 mm piston diameter, a 500 mm stroke, and an M12x1.25 external piston rod thread conforming to ISO 15552. Built with a piston, piston rod, and profile barrel structural design, it operates between 0.06 MPa and 1.2 MPa using compressed air per ISO 8573-1:2010 [7:4:4] and includes self-adjusting pneumatic end-position cushioning. The unit provides position sensing via proximity switch, achieves a theoretical retracting force of 633 N at 6 bar, and maintains high corrosion stress resistance along with ISO 14644-1 Class 5 cleanroom 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.
