Festo
5205900
Round cylinder DSNU-S-8-25-P-A-MQ
The Festo 5205900 is a double-acting industrial component featuring an 8 mm piston diameter, a 25 mm stroke, and an M4 piston rod thread with a structural design comprising a piston, piston rod, and cylinder barrel. It operates on compressed air per ISO 8573-1:2010 [7:4:4] within a pressure range of 0.15 MPa to 1 MPa (1.5 bar to 10 bar), utilizing elastic cushioning rings at both ends and position sensing via proximity switch. The unit provides a theoretical force of 30.2 N advancing and 22.6 N retracting at 6 bar, with an ambient temperature range of -20 °C to 80 °C, moderate corrosion resistance (CRC 2), and ISO Class 5 cleanroom suitability.

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.
