Swivel actuator unit DSL-16-40-270-P-A-S20-KF-B

The Festo 556591 is a double-acting rotary vane industrial component featuring a 16 mm piston diameter, a 40 mm stroke, and a swivel angle adjustment range from 0 to 270 degrees with a total swivel angle of 0 to 272 degrees. Operating at pressures between 2.5 bar and 8 bar using compressed air conforming to ISO 8573-1:2010 [7:4:4], this unit includes ball bearing-guided torsion protection, elastic cushioning rings or pads at both ends, and a through hollow piston rod. Position sensing is accomplished via proximity switch, supporting a maximum impact velocity of 500 mm/s, a maximum swivel frequency of 2 Hz at 6 bar, a precision adjustment of -6 degrees, a swivel angle backlash of 0.05 degrees, and a repetition accuracy of 1 degree.

Why 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.

Engineering context

Identification and RFQ Guidance

Confirm the exact configuration

Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
