Festo
177166
Swivel/linear unit DSL-16-40-270-P-S20-CC-KF
This Festo rotary vane industrial component operates with a double-acting mode using a 16 mm piston diameter, a 40 mm stroke, and a torque of 1.25 Nm at 6 bar within an operating pressure range of 2.5 to 8 bar. Featuring an S20 through, hollow piston rod, a ball-bearing guide, and a 238 deg swivel angle with a 270 deg rotation angle adjustment range, it incorporates CC shock absorbers and P flexible cushioning rings at both ends. The unit functions with dried compressed air in ambient temperatures from -10 to 60 °C, supporting inductive and proximity sensors for position detection.
