Festo
4921
Round cylinder EG-25-10
The Festo 4921 is a single-acting industrial component featuring a 25 mm piston diameter and a 10 mm stroke with a single-ended piston rod operating via a pushing action. This unit operates on compressed air conforming to ISO8573-1:2010 [7:4:4] within a working pressure range of 1 to 8 bar, delivering a theoretical force of 215 N at 6 bar during the advance stroke through a G1/8 pneumatic connection. Designed without cushioning or position detection across an ambient temperature range of -20 to 80 °C, it accommodates lubricated operation provided it is subsequently required for further operation.
