Festo
161040
Swivel/linear unit DSL-20-100-270-P-S20-FF
The Festo 161040 is a double-acting rotary vane industrial component featuring a 20 mm piston diameter, a 100 mm stroke, and an S20 through, hollow piston rod with a plain-bearing guide. It operates with dried compressed air at a pressure range of 2.5 to 8 bar, delivering a torque of 2.5 Nm at 6 bar with a maximum swivel frequency of 2 Hz and a max impact speed of 500 mm/s. The unit provides a swivel angle of 272 degrees, a rotation angle adjustment range of 270 degrees with 5 degrees of fine adjustment, flexible cushioning rings at both ends with a 2.1-degree cushioning angle and 5 mm cushioning length, and position detection compatibility for inductive and proximity sensors across any assembly position within an ambient temperature 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.
