Festo
556405
Swivel actuator unit DSL-16-50-270-P-A-S20-B
This Festo industrial component, part number 556405, is a double-acting rotary vane structural design featuring a 16 mm piston diameter, a 50 mm stroke, and a swivel angle adjustment range from 0 deg to 270 deg with a maximum swivel angle of 272 deg. It operates within a pressure range of 2.5 bar to 8 bar utilizing compressed air as per ISO 8573-1:2010 [7:4:4], and incorporates elastic cushioning rings or pads at both ends alongside position sensing via proximity switch. The unit includes a through, hollow piston rod, plain bearing-guide torsion protection, a -6 deg precision adjustment, 2 deg swivel angle backlash, 1 deg repetition accuracy, a maximum impact velocity of 500 mm/s, and a maximum swivel frequency of 2 Hz at 6 bar in any mounting position under CRC 1 low corrosion stress.
