Festo
14321
ISO cylinder DSNU-20- -PPV-A
The Festo 14321 is a double-acting industrial component featuring a 20 mm piston diameter, an M8 piston rod thread, and an adjustable pneumatic cushioning at both ends with a 15 mm cushioning length. Conforming to CETOP RP 52 P and ISO 6432 standards, this variant includes a single-ended external piston rod, position sensing via proximity switch, and a stroke length ranging from 1 mm to 320 mm. It operates within a pressure range of 0.1 MPa to 1 MPa using compressed air conforming to ISO 8573-1:2010 [7:4:4], supports oil lubrication, and maintains moderate corrosion resistance class (CRC) 2 within an ambient temperature range of -20 °C to 80 °C.

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.
