Festo
The Festo 556403 is a double-acting industrial component featuring a rotary vane structural design with a 16 mm piston diameter, a 50 mm stroke, and an adjustable swivel angle ranging from 0 deg to 246 deg. This unit operates within a 2.5 bar to 8 bar pressure range using compressed air as per ISO 8573-1:2010 [7:4:4], incorporating both pneumatic shock absorbers and elastic cushioning rings at both ends along with a 15 deg cushioning angle. Built with a through piston rod and plain bearing-guide torsion protection, it achieves a 0.1 deg repetition accuracy, a 2 deg swivel angle backlash, a -3 deg precision adjustment, and a maximum swivel frequency of 1.5 Hz at 6 bar with a 500 mm/s max impact velocity. Position sensing is accomplished via a proximity switch, and operation with oil lubrication is possible and required for further use in any mounting position.
