Festo
11656
Standard cylinder ESN-25- -P
The Festo part number 11656 is a single-acting industrial component with a 25 mm piston diameter, a stroke length ranging from 1 to 50 mm, and a pushing action mode of operation driven by compressed air conforming to ISO 8573-1:2010 [7:4:4]. Built with flexible cushioning rings at both ends, a male M10x1.25 piston rod thread, and a single-ended piston rod design adhering to CETOP RP 52 P and ISO 6432 standards, this unit operates within a 1.2 to 10 bar working pressure and a -20 to 80 °C ambient temperature range. It delivers a theoretical force of 270 N at 6 bar advance stroke while featuring a CRC 2 moderate corrosion resistance classification, a moving mass of 238 g at 0 mm stroke, and an additional weight of 10.9 g per 10 mm stroke.
