Festo
556727
Swivel actuator unit DSL-40-25-270-CC-A-S2-KF-B
The Festo 556727 is a double-acting rotary vane industrial component featuring a 40 mm piston diameter, a 25 mm stroke, and a ball bearing-guided structure with a through piston rod for universal installation in any mounting position. Operating at pressures from 2.5 bar to 8 bar with compressed air conforming to ISO 8573-1:2010 [7:4:4], this unit provides an adjustable swivel angle of 0 deg to 240 deg with a 16 deg cushioning angle, -3 deg precision adjustment, 0.05 deg swivel angle backlash, and 0.1 deg repetition accuracy. Cushioning is handled by a pneumatic shock absorber and elastic cushioning rings at both ends, while position sensing occurs via proximity switch up to a max impact velocity of 500 mm/s and a max swivel frequency of 0.7 Hz at 6 bar.

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.
