Festo
556640
Swivel actuator unit DSL-20-80-270-CC-A-S20-KF-B
The Festo part number 556640 is a double-acting rotary vane industrial component featuring a 20 mm piston diameter, an 80 mm stroke, and an adjustable swivel angle ranging from 0 deg to 246 deg with a 12 deg cushioning angle. It utilizes pneumatic shock absorbers and elastic cushioning rings at both ends, a ball bearing-guided through, hollow piston rod, and proximity switch position sensing. Operating on compressed air per ISO 8573-1:2010 [7:4:4] within a 2.5 bar to 8 bar pressure range, this unit achieves a maximum impact velocity of 500 mm/s, a 0.1 deg repetition accuracy, and a 0.05 deg swivel angle backlash in any mounting position.
