Festo
556544
Swivel actuator unit DSL-40-40-270-CC-A-S20-B
The Festo 556544 is a double-acting industrial component featuring a rotary vane structural design with a 40 mm piston diameter and a 40 mm stroke. Operating within a pressure range of 2.5 bar to 8 bar using compressed air as per ISO 8573-1:2010 [7:4:4], this unit provides a 0 deg to 240 deg swivel angle with a 16 deg cushioning angle, a -3 deg precision adjustment, and dual pneumatic shock absorbers and elastic cushioning rings at both ends. It includes position sensing via proximity switch, a through hollow piston rod, a plain bearing-guide for torsion protection, a 500 mm/s max impact velocity, and a 0.7 Hz max swivel frequency at 6 bar.

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.
