Festo
2159639
ISO cylinder CRDSNU-B-25-50-PPS-A-MG-A1
The Festo 2159639 is a double-acting industrial component featuring a 25 mm piston diameter, a 50 mm stroke, and a structural design comprising a piston, piston rod, and cylinder barrel based on the ISO 6432 norm. Designed for operation with compressed air as per ISO 8573-1:2010 [7:4:4] within a pressure range of 1 bar to 10 bar, this unit delivers a theoretical force of 295 N advancing and 247 N retracting at 6 bar. It incorporates self-adjusting pneumatic end-position cushioning, position sensing via proximity switch, and a corrosion resistance class of 4 for particularly high corrosion stress while operating in ambient temperatures from 0 °C to 80 °C.

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.
