Festo
556495
Swivel actuator unit DSL-25- -270-P-A-S20-B
The Festo 556495 is a double-acting rotary vane industrial component featuring a 25 mm piston diameter, a 10 mm to 160 mm stroke, and a swivel angle adjustment range from 0 degrees to 270 degrees with a maximum angle of 272 degrees. Operating on compressed air according to ISO 8573-1:2010 [7:4:4] at pressures between 2.5 bar and 8 bar, this unit incorporates elastic cushioning rings at both ends, a plain bearing-guide for torsion protection, and a through, hollow piston rod variant. It achieves a repetition accuracy of 1 degree, a swivel angle backlash of 2 degrees, a maximum impact velocity of 500 mm/s, and a maximum swivel frequency of 2 Hz at 6 bar, with position sensing facilitated via proximity switch 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.
