Festo
546399
Round cylinder DSNU-3/8"-1/2"-P-A
The Festo 546399 is a double-acting industrial component with a 3/8" piston diameter and a 0.5 in stroke, built on the ISO 6432 norm with elastic cushioning rings at both ends. Designed with an external 6-32 UNC-2A piston rod thread at one end, it features position sensing via proximity switch, operates within a pressure range of 1 bar to 10 bar, and delivers theoretical forces of 8.9 lbf retracting and 10.6 lbf advancing at 6 bar. This unit supports compressed air operating media per ISO 8573-1:2010 [7:4:4] with optional oil lubrication, a moderate corrosion resistance class (CRC 2), and 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.
