Festo
177203
Swivel/linear unit DSL-20- -270-P-S2-FF-KF
The Festo 177203 is a double-acting rotary vane industrial component featuring a 20 mm piston diameter, a 272 degree swivel angle with a 270 degree rotation angle adjustment range, and a 2.5 Nm torque output at 6 bar. This unit operates within a 2.5 to 8 bar pressure range on dried compressed air, delivers a cushioning angle of 2.1 degrees via flexible cushioning rings at both ends, and includes a ball-bearing guide for torque protection. Designed with an adjustable stroke from 10 to 100 mm and compatibility with proximity or inductive sensors, it functions in any assembly position under ambient temperatures between -10 and 60 degrees Celsius.
