Festo
170121
Standard cylinder DSNU-8- -P-A-CT
This Festo double-acting industrial component features an 8 mm piston diameter, an adjustable stroke length from 10 to 100 mm, and an M4 male piston rod thread conforming to ISO 6432. Built with flexible cushioning rings at both ends, a working pressure range of 1 to 10 bar, and a CRC 2 corrosion resistance classification, it operates on dried compressed air across an ambient temperature range of -20 to 80 °C. The unit includes position detection for proximity sensors, copper- and PTFE-free variants (CT), Germanischer Lloyd authorization, and delivers theoretical forces of 30.2 N on advance stroke and 22.6 N on return stroke at 6 bar.

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.
