Festo
159571
Swivel/linear unit DSL-25- -270-P-S20-FF
The Festo 159571 is a double-acting rotary vane industrial component featuring a 25 mm piston diameter, an adjustable rotation angle range of 270 degrees, a swivel angle of 272 degrees, and a 5 Nm torque output at 6 bar. Operating within a pressure range of 2.5 to 8 bar and temperatures from -10 to 60 °C, this unit uses flexible cushioning rings or plates at both ends with a 1.9 degree cushioning angle, a 5 mm cushioning length, and a 5 degree fine adjustment. It includes a plain-bearing guide for torque protection, a through hollow piston rod in the S20 variant, and provisions for inductive or proximity sensor position detection using dried compressed air.

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.
