Festo
The Festo 4186566 industrial component is a double-acting and single-acting unit featuring a 16 mm piston diameter, an adjustable stroke from 5 mm to 50 mm, and elastic cushioning rings or pads at both ends. Operating on compressed air per ISO 8573-1:2010 [7:4:4] within a 1.5 bar to 8 bar pressure range, this profile barrel actuator achieves a theoretical force of 104 N to 121 N at 6 bar and functions in ambient temperatures from -10 °C to 120 °C. The design incorporates a guide rod with yoke for torsion protection, position sensing via proximity switch, and construction suitable for Li-ion battery production under VDMA24364-B2-L conformity and ISO 14644-1 cleanroom Class 6.
