Festo
The Festo 4840823 is a single-acting industrial component featuring a 20 mm piston diameter, a 15 mm stroke, and a profile barrel structural design with a guide rod and yoke for torsion protection. Operating on compressed air within a pressure range of 0.2 MPa to 0.8 MPa, this unit delivers a theoretical advancing force of 160 N at 6 bar and incorporates elastic cushioning rings at both ends. It supports position sensing via proximity switch, features moderate corrosion resistance (CRC 2), and meets ISO 14644-1 cleanroom Class 6 standards across an ambient temperature range of -10 °C to 80 °C.
