Festo
546420
Round cylinder DSNU-1"-8"-PPV-A
The Festo 546420 is an ISO 6432 compliant, double-acting industrial component featuring a 1-inch piston diameter, an 8-inch stroke, and a 3/8-24 UNF-2A piston rod thread at one end. Designed with adjustable pneumatic cushioning at both ends, a 0.67-inch cushioning length, and a 0.221 ft-lbf impact energy tolerance in the end positions, this unit operates between 1 bar and 10 bar using compressed air conforming to ISO 8573-1:2010 [7:4:4]. It delivers a theoretical retracting force of 55.6 lbf at 6 bar, accommodates any mounting position, allows position sensing via proximity switch, and maintains a CRC 2 moderate corrosion resistance rating across an ambient temperature range of -4 °F to 176 °F.

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.
