Festo
556499
Swivel actuator unit DSL-32-25-270-CC-A-S2-B
The Festo part number 556499 is a double-acting rotary vane industrial component featuring a 32 mm piston diameter, a 25 mm stroke, and a swivel angle adjustment range of 0 deg to 246 deg with a 12 deg cushioning angle. It utilizes a pneumatic shock absorber and elastic cushioning rings at both ends, a plain bearing-guide for torsion protection, and permits position sensing via a proximity switch within an operating pressure range of 2.5 bar to 8 bar. Operating on compressed air compliant with ISO 8573-1:2010 [7:4:4], this through piston rod variant includes a 0.1 deg repetition accuracy, a 2 deg swivel angle backlash, a -3 deg precision adjustment, and a maximum impact velocity of 500 mm/s.

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.
