New Original Festo DSR‑32‑180‑‑P (Part‑No:11912) Semi‑Rotating Cylinder
1. Product Overview
The DSR‑32‑180‑‑P is a rack‑and‑pinion‑type semi‑rotating cylinder developed and manufactured by Festo Germany. It is a genuine original new‑condition actuator designed to convert linear piston motion into rotary output movement. This unit is widely deployed for angular positioning and swing‑rotation tasks within automated assembly equipment, sorting machinery, gripping stations, packaging machines and material‑transfer jigs. Its preset swing angle is fixed at 180°, and the model size is 32‑mm bore. The suffix‑P means the cylinder is equipped with adjustable end‑position cushioning at both rotating ends for shock absorption. The part number 11912 is the unique factory‑assigned code for DSR‑32‑180‑P, with completely original internal components including high‑strength gear‑pinion set, wear‑resistant piston seals, corrosion‑resistant housing and precision‑machined output shaft. Only filtered compressed air is allowed as the working medium.
2. Main Functions
- Converts straight‑line piston push‑pull movement into stable rotational motion with a maximum swing angle of 180‑degree.
- Adjustable pneumatic end‑of‑stroke cushioning lessens impact noise and reduces mechanical wear when rotation finishes.
- The splined output‑shaft transmits torque to external fixtures, clamps or rotating arms reliably.
- Compatible with external proximity sensors to detect the two limit rotational positions for electrical signal feedback in automatic control loops.
- Delivers consistent output torque within the rated working‑pressure range to satisfy medium‑load rotating‑positioning requirements.
- Simple air‑port layout supports double‑action working principle: forward air‑supply for clock‑wise rotation and reverse air‑supply for counter‑clockwise rotation.
