Festo
156865
Compact cylinder ADVUL-20-50-P-A
The Festo 156865 is a double-acting industrial component featuring a 20 mm piston diameter, a 50 mm stroke, and a piston rod at one end configured with a guide rod and yoke for torsion protection. Operating within a pressure range of 1 to 10 bar utilizing compressed air per ISO 8573-1:2010 [7:4:4], this unit incorporates elastic cushioning rings at both ends and position sensing via proximity switch. It delivers a theoretical force of 188 N advancing and 141 N retracting at 6 bar while withstanding ambient temperatures from -20 °C to 80 °C with a CRC 2 moderate corrosion stress rating.

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.
