Festo
156551
Compact cylinder ADVU-50-15-P-A
The Festo 156551 is a double-acting industrial component featuring a 50 mm piston diameter, a 15 mm stroke, and an internal M8 piston rod thread at one end. Designed with elastic cushioning rings at both ends, it operates within a pressure range of 0.08 MPa to 1 MPa using compressed air according to ISO 8573-1:2010 [7:4:4], with oil lubrication permitted. This unit provides position sensing via proximity switch, a corrosion resistance class of 2, an ambient temperature range of -20 °C to 80 °C, and delivers theoretical forces of 1057 N retracting and 1178 N advancing 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.
