Festo
556520
Swivel actuator unit DSL-32-80-270-CC-A-S20-B
The Festo industrial component, part number 556520, is a double-acting rotary vane structural design featuring a 32 mm piston diameter, an 80 mm stroke, and a swivel angle adjustment range of 0 deg to 246 deg with a 12 deg cushioning angle. Equipped with pneumatic shock absorbers and elastic cushioning rings at both ends, a through hollow piston rod, and a plain bearing-guide, this unit operates within a pressure range of 2.5 bar to 8 bar using compressed air as per ISO 8573-1:2010 [7:4:4]. It delivers a repetition accuracy of 0.1 deg, a maximum swivel frequency of 0.7 Hz at 6 bar, and position sensing via proximity switch, with oil lubrication permitted.

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.
