Name: Festo 546421 Round cylinder DSNU-1"-3"-PPV-A
Brand: Festo

Round cylinder DSNU-1"-3"-PPV-A

The Festo 546421 is a double-acting industrial component built to ISO 6432 standards featuring a 1-inch piston diameter, a 3-inch stroke, and a 3/8-24 UNF-2A external piston rod thread at one end. Operating on compressed air according to ISO 8573-1:2010 [7:4:4] within a 1 bar to 10 bar pressure range, this unit incorporates adjustable pneumatic cushioning at both ends with a 0.67-inch cushioning length and 0.221 ft-lbf end-position impact energy. It delivers a theoretical retracting force of 55.6 lbf at 6 bar, accommodates any mounting position with position sensing via proximity switch, and offers moderate corrosion resistance (CRC 2) across an ambient temperature range of -4 °F to 176 °F.

Why 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.

Identification and RFQ Guidance

Confirm the exact configuration

Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
