Name: Festo 574405 Rotary actuator DRRD-50-
Brand: Festo

Rotary actuator DRRD-50-

The Festo part number 574405 is a double-acting industrial component featuring a size 50 design, a 180-degree swivel angle, and a gear rack/pinion structural design with internal hydraulic cushioning (normal and hard) and external hydraulic cushioning. Operating on compressed air as per ISO 8573-1:2010 [7:4:4] within a pressure range of 0.2 MPa to 1 MPa (2 bar to 10 bar), this unit allows for any mounting position, one intermediate position, and position sensing via a proximity switch, with oil lubrication permitted and required for continued use. Certified for explosive atmospheres in ATEX and UKEX Zone 1, Zone 2, Zone 21, and Zone 22, the component carries CE, UKEX, and EPL Db/Gb markings with an explosive ambient temperature range of -10°C to +60°C, gas ignition protection Ex h IIC T4 Gb (ATEX category II 2G), and dust ignition protection Ex h IIIC T120°C Db (ATEX category II 2D).

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.
