Festo
556685
Swivel actuator unit DSL-25- -270-CC-A-S2-KF-B
The Festo part number 556685 is a double-acting rotary vane industrial component featuring a 25 mm piston diameter, a 10 mm to 100 mm stroke, and a swivel angle range of 0 deg to 246 deg with a precision adjustment of -3 deg. This ball bearing-guided unit operates at pressures between 2.5 bar and 8 bar using compressed air as per ISO 8573-1:2010 [7:4:4], incorporating pneumatic shock absorbers and elastic cushioning rings at both ends alongside position sensing via proximity switch. Featuring a through piston rod variant, a max impact velocity of 500 mm/s, and a maximum swivel frequency of 1 Hz at 6 bar, it maintains a swivel angle backlash of 0.05 deg and a repetition accuracy of 0.1 deg in any mounting position.

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.
