Festo
556474
Swivel actuator unit DSL-25-50-270-P-A-S2-B
The Festo part number 556474 is a double-acting industrial component featuring a rotary vane structural design with a 25 mm piston diameter, a 50 mm stroke, and an adjustable swivel angle ranging from 0 degrees to 270 degrees (with a 0 degrees to 272 degrees swivel angle and −6 degrees precision adjustment). It operates on compressed air as per ISO 8573-1:2010 [7:4:4] at pressures between 2.5 bar and 8 bar, incorporating elastic cushioning rings/pads at both ends, a plain bearing-guide for torsion protection, through piston rod variants, and position sensing via proximity switch. The unit delivers a maximum impact velocity of 500 mm/s, a maximum swivel frequency of 2 Hz at 6 bar, a 2-degree swivel angle backlash, a 1-degree repetition accuracy, and a corrosion resistance class of CRC 1 for low corrosion stress in any mounting position.
