Festo
556393
Swivel actuator unit DSL-16-25-270-P-A-S20-B
The Festo part number 556393 is a double-acting rotary vane industrial component featuring a 16 mm piston diameter, a 25 mm stroke, and an adjustable swivel angle from 0 to 270 degrees with a precision adjustment of -6 degrees. Operating on compressed air per ISO 8573-1:2010 [7:4:4] within a pressure range of 2.5 bar to 8 bar, this unit incorporates elastic cushioning rings at both ends, a through hollow piston rod, a plain bearing-guide for torsion protection, and proximity switch position sensing. It achieves a maximum swivel frequency of 2 Hz at 6 bar, a maximum impact velocity of 500 mm/s, a 2-degree swivel angle backlash, a 1-degree repetition accuracy, and a corrosion resistance class of 1 under low corrosion stress, while allowing optional oil lubrication.

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.
