Festo
177278
Swivel/linear unit DSL-40-125-270-P-S20-CC-KF
This Festo rotary vane industrial component, part number 177278, operates in a double-acting mode with a 40 mm piston diameter, a 125 mm stroke, and a 240 deg swivel angle within a 270 deg rotation angle adjustment range. The unit features a ball-bearing guide, a through hollow piston rod, CC shock absorbers and P flexible cushioning rings at both ends, a 15 deg cushioning angle, a 12 mm cushioning length, and a 1.5 deg fine adjustment. Powered by dried compressed air at an operating pressure of 2.5 to 8 bar, it delivers 20 Nm of torque at 6 bar with a maximum impact speed of 500 mm/s and a maximum swivel frequency of 0.7 Hz at 6 bar across an ambient temperature range of -10 to 60 °C in any assembly position with position detection for inductive and proximity sensors.
