Festo
1779439
ISO cylinder DSBF-C-40-250-PPSA-N3-R
This Festo double-acting industrial component features a 40 mm piston diameter, a 250 mm stroke, and an M12x1.25 external piston rod thread, operating within a pressure range of 0.06 MPa to 1.2 MPa. Built with a profile barrel structural design conforming to ISO 15552, it utilizes self-adjusting pneumatic end-position cushioning, position sensing via proximity switch, and operates with compressed air according to ISO 8573-1:2010 [7:4:4] under ambient temperatures from -20 °C to 80 °C. The unit achieves a corrosion resistance class of 3 for high corrosion stress, VDMA24364-B2-L LABS conformity, and ISO 14644-1 Class 5 cleanroom suitability, delivering a theoretical force of 633 N at 6 bar retracting.

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.
