Festo
156121
Compact cylinder ADVULQ-16- -P-A-S26
The Festo 156121 is a double-acting industrial component featuring a 16 mm piston diameter, a square piston rod for torque protection, and an adjustable stroke ranging from 1 to 200 mm. Operating on compressed air compliant with ISO8573-1:2010 [7:4:4] within a pressure range of 0.13 to 1 MPa (1.5 to 10 bar or 18.85 to 145 psi), this unit incorporates flexible cushioning rings at both ends and heat-resistant seals rated up to 120°C. It delivers a theoretical retracting force of 90 N at 0.6 MPa (6 bar, 87 psi) and includes position detection capabilities for proximity sensors alongside a through piston rod design.

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.
