Festo
177165
Swivel/linear unit DSL-16-40-270-P-S20-FF-KF
The Festo 177165 is a double-acting rotary vane industrial component featuring a 16 mm piston diameter, 40 mm stroke, and a ball-bearing guide for torque and guide protection. Operating at pressures from 2.5 to 8 bar with dried compressed air, it delivers a torque of 1.25 Nm at 6 bar, a swivel angle of 272 degrees, and a maximum swivel frequency of 2 Hz. This variant includes a through, flexible hollow piston rod, 270-degree rotation angle adjustment range, 5-degree fine adjustment, 2.6-degree cushioning angle, and flexible cushioning rings or plates at both ends with a 4.5 mm cushioning length. Designed for ambient temperatures between -10 and 60 °C and compatible with inductive or proximity sensors, it functions in any assembly position at a maximum impact speed of 500 mm/s.
