Festo
556493
Swivel actuator unit DSL-25- -270-CC-A-S2-B
This Festo industrial component, part number 556493, is a double-acting rotary vane structural design featuring a 25 mm piston diameter, a 10 mm to 160 mm stroke, and a swivel angle adjustment range of 0 degrees to 246 degrees with a 10-degree cushioning angle. Equipped with both pneumatic shock absorbers and elastic cushioning rings at both ends, a plain bearing-guide for torsion protection, and through piston rod variants, it operates on compressed air per ISO 8573-1:2010 [7:4:4] within an operating pressure of 2.5 bar to 8 bar. Position sensing occurs via a proximity switch, achieving a 0.1-degree repetition accuracy, a 2-degree swivel angle backlash, a -3-degree precision adjustment, a maximum impact velocity of 500 mm/s, and a maximum swivel frequency of 1 Hz at 6 bar in any mounting position.
