Festo
556546
Swivel actuator unit DSL-40-50-270-P-A-S2-B
The Festo part number 556546 is a double-acting rotary vane industrial component featuring a 40 mm piston diameter, a 50 mm stroke, and a swivel angle ranging from 0 degrees to 272 degrees with an adjustment range of 0 degrees to 270 degrees. Equipped with elastic cushioning rings or pads at both ends, a plain bearing-guide for torsion protection, through piston rod variants, and position sensing via proximity switch, this unit operates on compressed air as per ISO 8573-1:2010 [7:4:4] at pressures between 2.5 bar and 8 bar. It achieves a maximum impact velocity of 500 mm/s, a maximum swivel frequency of 2 Hz at 6 bar, a precision adjustment of -6 degrees, a swivel angle backlash of 2 degrees, and a repetition accuracy of 1 degree within a corrosion resistance class of CRC 1.
