The STROMAG Periflex® VN23011 belongs to the well‑known Periflex® VN series, a high‑performance elastomer disc coupling optimised for diesel‑engine‑driven powertrains. It features linear torsional spring characteristics, delivering outstanding torsional‑vibration damping and shock‑absorbing performance to protect engines, generators and connected equipment from harmful dynamic loads.
Adopting proven axial plug‑in blind‑assembly design, the coupling can be mounted and the rubber disc tyre replaced without dismantling adjacent machinery, greatly cutting on‑site maintenance time. It compensates axial, radial and angular shaft misalignment simultaneously, lowering assembly‑precision requirements and reducing premature wear on bearings and shafts.
Two elastomer material options are available:
- **NR (Natural Rubber)**: ‑50 °C ~ +80 °C, good damping performance for standard working conditions
- **ECO heat‑resistant compound**: ‑40 °C ~ +120 °C, excellent oil‑proof and ozone‑resistant properties for high‑temperature marine and heavy‑duty environments
