Festo
193990
ISO cylinder DSNU-20- -
The Festo 193990 is a double-acting industrial component featuring a 20 mm piston diameter, an adjustable stroke ranging from 1 mm to 320 mm, and an operating pressure of 0.1 MPa to 1 MPa (1 bar to 10 bar). Conforming to ISO 6432 and CETOP RP 52 P standards, this unit incorporates a piston, piston rod, and cylinder barrel with options for elastic, self-adjusting pneumatic, or adjustable pneumatic cushioning at both ends, alongside position sensing via a proximity switch and an optional square piston rod for torsion protection. Certified for use in ATEX and UKEX Zone 1, Zone 2, and Zone 21 explosive atmospheres with corresponding EPL Gb and EPL Db ratings, the assembly supports universal mounting positions and numerous variants including increased chemical resistance, weld spatter protection, and low-friction configurations.

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.
