Festo
556481
Swivel actuator unit DSL-25-80-270-CC-A-S2-B
The Festo 556481 is a double-acting industrial component featuring a rotary vane structural design with a 25 mm piston diameter, an 80 mm stroke, and an adjustable swivel angle ranging from 0 deg to 246 deg. This unit operates within an air pressure range of 2.5 bar to 8 bar using compressed air according to ISO 8573-1:2010 [7:4:4], utilizing both pneumatic shock absorbers and elastic cushioning rings at both ends with a 10 deg cushioning angle. Equipped with a through piston rod, plain bearing-guide for torsion protection, and position sensing via proximity switch, it achieves a repetition accuracy of 0.1 deg and a max impact velocity of 500 mm/s.

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.
