Swivel actuator unit DSL-40-125-270-P-A-S20-B

The Festo part number 556567 is a double-acting rotary vane industrial component featuring a 40 mm piston diameter, a 125 mm stroke, and an adjustable swivel angle ranging from 0 degrees to 270 degrees with a maximum limit of 272 degrees and a -6 degree precision adjustment. Operating at a pressure range of 2.5 bar to 8 bar using compressed air conforming to ISO 8573-1:2010 [7:4:4], this unit incorporates elastic cushioning rings or pads at both ends, a through hollow piston rod, a plain bearing-guide for torsion protection, and position sensing via proximity switch. It delivers a maximum impact velocity of 500 mm/s, a maximum swivel frequency of 2 Hz at 6 bar, a swivel angle backlash of 2 degrees, and a repetition accuracy of 1 degree within a low corrosion stress CRC 1 rating, while permitting optional oil lubrication.

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.
