Festo
556459
Swivel actuator unit DSL-20- -270-P-A-S20-B
The Festo 556459 is a double-acting industrial component featuring a rotary vane structural design with a 20 mm piston diameter, a 10 mm to 160 mm stroke, and a swivel angle adjustment range from 0 degrees to 270 degrees. Built with a plain bearing-guide for torsion protection, elastic cushioning rings or pads at both ends, and a through, hollow piston rod, it operates on compressed air per ISO 8573-1:2010 [7:4:4] at pressures between 2.5 bar and 8 bar. This unit supports proximity switch position sensing, a maximum impact velocity of 500 mm/s, a maximum swivel frequency of 2 Hz at 6 bar, a 1-degree repetition accuracy, and a corrosion resistance class of CRC 1.

Request a QuoteWhy no listed price?
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.
