Festo
8148788
Round cylinder DSNU-S-20- -F1A-
The Festo 8148788 is a double-acting industrial component featuring a 20 mm piston diameter, an adjustable stroke from 1 mm to 200 mm, and an operating pressure range of 0.08 MPa to 1 MPa (0.8 bar to 10 bar). It utilizes elastic cushioning rings/pads alongside self-adjusting pneumatic end-position cushioning, providing a 15 mm cushioning length and 0.2 J impact energy in the end positions. Delivering a theoretical force of 188.5 N advancing and 158.3 N retracting at 6 bar, this unit supports compressed air operating media per ISO 8573-1:2010 [7:4:4] with optional oil lubrication. The assembly achieves ISO 14644-1 Cleanroom Class 5 suitability and VDMA24364-B2-L LABS conformity, while excluding specific copper, zinc, and nickel constituents to remain suitable for battery production with reduced Cu/Zn/Ni values (F1a).

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.
