Festo
This Festo industrial component (Part Number 8142891) is a double-acting piston actuator featuring a 40 mm piston diameter, a 30 mm stroke, and an external thread piston rod at one end. It operates within a pressure range of 0.06 MPa to 1 MPa (0.6 bar to 10 bar) using compressed air conforming to ISO 8573-1:2010 [7:4:4], delivering a theoretical advancing force of 754 N and a retracting force of 686 N at 6 bar. Constructed with elastic cushioning rings at both ends and rated for ISO Class 5 cleanrooms alongside reduced Cu/Zn/Ni battery production suitability (F1a), the unit functions in ambient temperatures from 0 °C to 80 °C with any mounting position.
