Festo
159549
Swivel/linear unit DSL-25-50-270-P-S2-FF
This Festo industrial component, part number 159549, is a double-acting rotary vane drive featuring a 25 mm piston diameter, a 50 mm stroke, and a 272 degree swivel angle with a 270 degree rotation angle adjustment range. Operating at pressures from 2.5 to 8 bar, it delivers 5 Nm of torque at 6 bar and incorporates 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. The unit includes a plain-bearing guide for torque protection, supports position detection via inductive and proximity sensors, accommodates an S2 through piston rod variant, and functions with dried compressed air within an ambient temperature range of -10 to 60 °C.

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.
