Festo DSR-40-180-P Rotary Cylinder

Festo DSR-40-180-P Rotary Cylinder, part number 13467, is a double-acting pneumatic rotary actuator from the DSR series designed for angular positioning and rotary actuation in automated systems. It delivers 0° to 180° of adjustable rotation with up to 20 Nm of theoretical torque at 6 bar, making it suitable for positioning, clamping, and directional changes driven by compressed air. The actuator operates at 1.5–8 bar and supports swivel frequencies up to 3 Hz, with a 20 mm shaft diameter and a G1/4 pneumatic connection. Mounting is through-hole, and both ends are elastically cushioned to dampen impact and extend life. Construction features a die-cast zinc housing and a steel shaft, and it is designed for industrial environments with an operating temperature range of -10 to +60 °C and ISO 8573-1 compliant compressed air. Typical applications include automated machinery, assembly lines, packaging equipment, robotic handling systems, indexing mechanisms, and material-handling processes requiring controlled rotary movement and precise angular positioning. For compatibility, common replacements include Festo DSRL-40-180-P-FW, Festo DSR-32-180-P, and Festo DRVS-40-180.
