Festo
185939
Rotary actuator DSM-8-180-P-A-FF-FW
The Festo 185939 is a size 8 double-acting rotary vane industrial component featuring an adjustable swivel angle range from 0 degrees to 180 degrees with a precision adjustment of -5 degrees and a 0-degree cushioning angle. Operating at pressures between 0.35 MPa and 0.8 MPa utilizing compressed air conforming to ISO 8573-1:2010 [7:4:4], this unit supports position sensing via proximity switch and achieves a maximum swivel frequency of 3 Hz at 6 bar with a repetition accuracy of 1 degree. It is rated for ambient temperatures from 0 °C to 60 °C, a permissible stop radius of 10 mm, a maximum stop force of 30 N, and a maximum axial force of 10 N in any mounting position.

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.
