Festo
177181
Swivel/linear unit DSL-16- -270-P-S20-FF-KF
The Festo 177181 is a double-acting rotary vane industrial component featuring a 16 mm piston diameter, a 2.6 degree cushioning angle, and a 272 degree swivel angle with a 270 degree rotation angle adjustment range. Operating at a pressure of 2.5 to 8 bar, this S20 variant utilizes a through, hollow piston rod, a ball-bearing guide for torque protection, and flexible cushioning rings or plates at both ends with a 4.5 mm cushioning length. It delivers a torque of 1.25 Nm at 6 bar, supports a maximum swivel frequency of 2 Hz, accommodates a maximum impact speed of 500 mm/s, and provides position detection for inductive or proximity sensors across an ambient temperature range of -10 to 60 °C using dried compressed air.
