Festo
544429
Linear actuator DGCI-63- -
The Festo 544429 is a double-acting industrial component featuring a 63 mm piston diameter, an adjustable stroke ranging from 100 mm to 2000 mm, and a recirculating ball bearing guide supporting any mounting position. Operating at pressures between 0.15 MPa and 0.8 MPa (1.5 bar to 8 bar), this unit incorporates pneumatic shock absorbers with hard and soft characteristic curves, a 35 mm stroke reduction in end positions, and position sensing via an attached linear potentiometer. It carries RCM compliance, CE and UKCA markings per EU and UK directives for EMC, RoHS, and explosion protection, along with ATEX and UKEX certifications for Zone 2 gas (II 3G) and Zone 22 dust (II 3D).

Request a QuoteWhy no listed price?
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
