Swivel actuator unit DSL-40-160-270-CC-A-S20-KF-B

The Festo 556766 is a double-acting rotary vane industrial component featuring a 40 mm piston diameter, a 160 mm stroke, and a swivel angle adjustment range of 0 deg to 240 deg with a 0.05 deg swivel angle backlash and 0.1 deg repetition accuracy. This ball bearing-guided unit includes a through, hollow piston rod, pneumatic shock absorbers and elastic cushioning rings at both ends, a 16 deg cushioning angle, a -3 deg precision adjustment, and position sensing via proximity switch. It operates on compressed air conforming to ISO 8573-1:2010 [7:4:4] at pressures between 2.5 bar and 8 bar, supporting a maximum impact velocity of 500 mm/s and a max swivel frequency of 0.7 Hz at 6 bar in any mounting position.

Why 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.
