Swivel actuator unit DSL-20- -270-CC-A-S2-KF-B

The Festo part number 556649 is a double-acting industrial component featuring a rotary vane structural design with a 20 mm piston diameter, a 10 mm to 100 mm stroke, and a 0 degree to 246 degree swivel angle. This ball bearing-guided unit operates on compressed air as per ISO 8573-1:2010 [7:4:4] within an operating pressure range of 2.5 bar to 8 bar, utilizing pneumatic shock absorbers and elastic cushioning rings at both ends with a 12 degree cushioning angle. Featuring position sensing via a proximity switch, a 0.05 degree swivel angle backlash, and a 0.1 degree repetition accuracy, the model supports a maximum impact velocity of 500 mm/s and a maximum swivel frequency of 1 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.
