Festo
556570
Swivel actuator unit DSL-40-160-270-P-A-S2-B
The Festo 556570 is a double-acting rotary vane industrial component featuring a 40 mm piston diameter, a 160 mm stroke, and a swivel angle ranging from 0 degrees to 272 degrees with a 0 degree to 270 degree adjustment range. This unit operates on compressed air as per ISO 8573-1:2010 [7:4:4] at pressures between 2.5 bar and 8 bar, utilizing elastic cushioning rings or pads at both ends, a plain bearing-guide for torsion protection, and a through piston rod variant. It achieves a maximum swivel frequency of 2 Hz at 6 bar, a max impact velocity of 500 mm/s, a 2 degree swivel angle backlash, a 1 degree repetition accuracy, and a -6 degree precision adjustment with position sensing via proximity switch in any mounting position under CRC 1 low corrosion stress.

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
