Festo
576156
Stopper cylinder DFSP-50-20-DF-PA
The Festo part number 576156 is a double-acting industrial component featuring a 50 mm piston diameter, a 20 mm stroke, and a round piston rod with an internal M8 thread. This profile barrel unit operates within a pressure range of 1 bar to 10 bar using compressed air conforming to ISO 8573-1:2010 [7:4:4], utilizing elastic cushioning rings at both ends and accommodating position sensing via a proximity switch in any mounting position. It achieves ISO 14644-1 Class 5 cleanroom suitability, VDMA24364-B1/B2-L LABS conformity, and a CRC 2 moderate corrosion resistance rating while supporting an ambient temperature range of -10 °C to 80 °C, a permissible impact force of 6280 N on the advanced piston rod, and a permissible lateral force of 1570 N during switching operations.

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.
