Semi-rotary actuator DRE-77-F10-Q12-FO-O-PS

The Festo 561977 is a single-acting rack and pinion industrial component featuring a size 77 actuator with a 90-degree swivel angle and an ISO 5211 compliant F10 flange hole pattern. It operates at a working pressure of 2 to 10 bar using compressed air meeting ISO8573-1:2010 [7:4:4] standards, allowing for subsequently required lubricated operation across any assembly position without position detection or cushioning. Certified under ATEX category II 2G for gas (c T6) and II 2D for dust (c 60°C) with an explosion-proof ambient temperature range of -20°C to +60°C, this unit includes a VDI/VDE 3845 NAMUR valve connection and a corrosion resistance classification CRC of 3.

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.
