Festo
556768
Swivel actuator unit DSL-40- -270-P-A-S2-KF-B
The Festo 556768 is a double-acting industrial component featuring a rotary vane structural design with a 40 mm piston diameter, a 10 mm to 160 mm stroke, and a swivel angle ranging from 0 deg to 272 deg with a 0.05 deg backlash. This unit incorporates ball bearing-guided torsion protection, elastic cushioning rings or pads at both ends, and a precision adjustment of -6 deg for operation within a 2.5 bar to 8 bar pressure range using ISO 8573-1:2010 [7:4:4] compressed air. Position sensing is accomplished via a proximity switch, supporting a maximum impact velocity of 500 mm/s and a 2 Hz swivel frequency at 6 bar in any mounting position.

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.
