Festo
556585
Swivel actuator unit DSL-16-25-270-P-A-S20-KF-B
The Festo 556585 is a double-acting industrial component featuring a rotary vane structural design with a 16 mm piston diameter, a 25 mm stroke, and an adjustable swivel angle ranging from 0 degrees to 270 degrees (with a total swivel angle of 0 degrees to 272 degrees, a -6 degree precision adjustment, and 0.05 degree swivel angle backlash). This model incorporates ball bearing-guided torsion protection, elastic cushioning rings or pads at both ends, proximity switch position sensing, through and hollow piston rod variants, and operates on compressed air per ISO 8573-1:2010 [7:4:4] within an operating pressure range of 2.5 bar to 8 bar. It achieves a maximum impact velocity of 500 mm/s, a maximum swivel frequency of 2 Hz at 6 bar, and a repetition accuracy of 1 degree while maintaining a corrosion resistance class (CRC) of 1 for low corrosion stress 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.
