Festo
556622
Swivel actuator unit DSL-20-25-270-CC-A-S20-KF-B
The Festo 556622 is a double-acting rotary vane industrial component featuring a 20 mm piston diameter, a 25 mm stroke, and a 0 deg to 246 deg swivel angle range with a 12 deg cushioning angle. Equipped with ball bearing-guided torsion protection, a through hollow piston rod, and dual pneumatic shock absorbers and elastic cushioning pads at both ends, this unit operates between 2.5 bar and 8 bar on compressed air conforming to ISO 8573-1:2010 [7:4:4]. Position sensing is achieved via proximity switch, delivering 0.1 deg repetition accuracy, 0.05 deg swivel angle backlash, and a -3 deg precision adjustment at a maximum impact velocity of 500 mm/s and 1 Hz swivel frequency at 6 bar.

Request a QuoteWhy no listed price?
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. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
