Brand: Festo

Semi-rotary actuator DRE-77-F10-Q10-FS-C

The Festo 190281 is a single-acting rack and pinion industrial component featuring an actuator size of 77 and a 90-degree swivel angle with no cushioning or position detection. Constructed with an ISO 5211 compliant F10 flange hole pattern and a VDI/VDE 3845 NAMUR valve connection, this unit operates on compressed air meeting ISO 8573-1:2010 [7:4:4] standards within a working pressure range of 2 to 10 bar in any assembly position. It carries ATEX certification for gas (II 2G c T6) and dust (II 2D c 60°C) across an explosion-proof ambient temperature range of -20°C to +60°C, utilizing spring force for the closing direction and allowing lubricated operation.

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.
