Festo
164825
Swivel/linear unit DSL-16-40-270-P-S20-CR
The Festo 164825 is a double-acting industrial rotary vane component featuring a 16 mm piston diameter, a 40 mm stroke, and a swivel angle of 254 degrees with a 270-degree rotation angle adjustment range. Operating at pressures from 2.5 to 8 bar, this unit delivers a torque of 1.25 Nm at 6 bar and includes a plain-bearing guide, a hollow through piston rod, and combined cushioning via a right shock absorber and flexible rings at both ends. It functions with dried compressed air within an ambient temperature range of -10 to 60 °C, supporting a maximum swivel frequency of 1.5 Hz at 6 bar and position detection using inductive or proximity sensors.
