Semi-rotary actuator DRD-77-F12

The Festo 189769 is a double-acting rack and pinion industrial component featuring a size 77 actuator with a 90-degree swivel angle and an ISO 5211 F12 flange hole pattern. Operating within a 2 to 10 bar working pressure range using compressed air compliant with ISO 8573-1:2010 [7:4:4], this un-cushioned unit operates in any assembly position without position detection and includes a VDI/VDE 3845 NAMUR valve connection and a corrosion resistance classification of 3. Certified with a CE symbol according to the EU-Ex protection guideline, it meets ATEX category II 2G for gas with c T6 protection and category II 2D for dust with c 60°C protection for an ambient temperature range of -20°C to +60°C, supporting lubricated operation if subsequently maintained.

Why 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.
