Swivel actuator unit DSL-20-80-270-CC-A-S20-B

This double-acting Festo industrial component features a 20 mm piston diameter, an 80 mm stroke, and a rotary vane structural design with a 0 deg to 246 deg swivel angle range. It operates on compressed air as per ISO 8573-1:2010 [7:4:4] within an operating pressure range of 2.5 bar to 8 bar, utilizing pneumatic shock absorbers and elastic cushioning rings at both ends along with a plain bearing-guide for torsion protection. The unit incorporates through, hollow piston rods, position sensing via proximity switch, a 12 deg cushioning angle, a -3 deg precision adjustment, and a 0.1 deg repetition accuracy.

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.

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.
