Festo
177186
Swivel/linear unit DSL-20-25-270-P-S20-CC-KF
The Festo part number 177186 is a double-acting rotary vane industrial component featuring a 20 mm piston diameter, 25 mm stroke, and a 238 degree swivel angle with a 270 degree rotation angle adjustment range. Operating at pressures from 2.5 to 8 bar, this S20 variant includes a through, hollow piston rod, a ball-bearing guide for torque protection, and both flexible cushioning rings and shock absorbers at both ends providing a 5 mm cushioning length and 12 degree cushioning angle. It functions with dried compressed air within an ambient temperature range of -10 to 60 °C, delivering a torque of 2.5 Nm at 6 bar, a maximum impact speed of 500 mm/s, and a maximum swivel frequency of 1 Hz. Position detection is supported for both inductive and proximity sensors, while the design allows for any assembly position and a 1.5 degree fine adjustment.
