Festo
556681
Swivel actuator unit DSL-25-100-270-P-A-S20-KF-B
The Festo part number 556681 is a double-acting industrial component featuring a rotary vane structural design with a 25 mm piston diameter, a 100 mm stroke, and a ball bearing-guided mechanism providing torsion protection and a through, hollow piston rod. Operating on compressed air per ISO 8573-1:2010 [7:4:4] within a 2.5 bar to 8 bar pressure range, this unit includes elastic cushioning rings at both ends, position sensing via proximity switch, and a swivel angle adjustment range from 0 deg to 270 deg with a max swivel angle of 272 deg at 6 bar and 2 Hz. Featuring a repetition accuracy of 1 deg, a swivel angle backlash of 0.05 deg, a precision adjustment of -6 deg, and a low corrosion stress CRC rating of 1, it supports optional oil lubrication and a maximum impact velocity of 500 mm/s in any mounting position.
