Festo
556679
Swivel actuator unit DSL-25-100-270-CC-A-S2-KF-B
The Festo 556679 is a double-acting industrial component featuring a rotary vane structural design with a 25 mm piston diameter, a 100 mm stroke, and a ball bearing-guided mechanism providing torsion protection. This unit operates at a pressure range of 2.5 bar to 8 bar using compressed air according to ISO 8573-1:2010 [7:4:4], offering a swivel angle adjustment range of 0 deg to 246 deg, a 10 deg cushioning angle, pneumatic shock absorbers and elastic cushioning pads at both ends, and position sensing via proximity switch. It achieves a repetition accuracy of 0.1 deg, a swivel angle backlash of 0.05 deg, a precision adjustment of -3 deg, a max impact velocity of 500 mm/s, and a max swivel frequency of 1 Hz at 6 bar with any mounting position and through piston rod variants.
