Festo
556541
Swivel actuator unit DSL-40-40-270-CC-A-S2-B
The Festo 556541 is a double-acting rotary vane industrial component featuring a 40 mm piston diameter, a 40 mm stroke, and a swivel angle adjustment range of 0 degrees to 240 degrees with a 16 degree cushioning angle and a -3 degree precision adjustment. This unit incorporates pneumatic shock absorbers and elastic cushioning rings at both ends, a plain bearing-guide for torsion protection, and position sensing via a proximity switch for an operating pressure range of 2.5 bar to 8 bar using compressed air as per ISO 8573-1:2010 [7:4:4].

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.
