Festo
556666
Swivel actuator unit DSL-25-50-270-P-A-S2-KF-B
This Festo part number 556666 is a double-acting rotary vane industrial component featuring a 25 mm piston diameter, a 50 mm stroke, and an adjustable swivel angle ranging from 0 degrees to 270 degrees with a -6 degree precision adjustment and 0.05 degree swivel angle backlash. Operating on compressed air as per ISO 8573-1:2010 [7:4:4] within a pressure range of 2.5 bar to 8 bar, the unit includes elastic cushioning rings or pads at both ends, ball bearing-guided torsion protection, a through piston rod, and position sensing via proximity switch. It delivers a maximum impact velocity of 500 mm/s, a maximum swivel frequency of 2 Hz at 6 bar, a repetition accuracy of 1 degree, and a low corrosion stress rating of CRC 1 with optional oil lubrication.
