Festo
556396
Swivel actuator unit DSL-16-40-270-P-A-S2-B
The Festo 556396 is a double-acting rotary vane industrial component featuring a 16 mm piston diameter, a 40 mm stroke, and an adjustable swivel angle ranging from 0 degrees to 270 degrees with a -6 degree precision adjustment and 2 degree backlash. Designed with elastic cushioning rings at both ends, a plain bearing-guide for torsion protection, and through piston rod variants, this unit operates on compressed air from 2.5 bar to 8 bar with position sensing via proximity switch. It achieves a maximum swivel frequency of 2 Hz at 6 bar, a repetition accuracy of 1 degree, and a maximum impact velocity of 500 mm/s under a corrosion resistance class of 1.

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.
