PUDZ III Heavy-Duty Hydraulic Buffer | Robust Shock Absorber

Hubner Australia proudly represents Römer Fördertechnik GmbH (RFT Germany) to bring you the PUDZ III Heavy-Duty Hydraulic Buffer—a rugged, high-performance shock absorber designed for extreme industrial demands.

🔧 Core Features & Advantages

  • Engineered & built in Germany 🇩🇪
    Precision-crafted by RFT for optimal performance and reliability

  • High-capacity energy absorption
    Available in piston diameters Ø 63 – 160 mm, stroke lengths 50 – 1,600 mm, and energy absorption up to 582 kJ per stroke, handling forces up to 1,000 kN

  • Progressive cushioning & piston accumulator
    Nitrogen-filled piston accumulator ensures a rising restoring force at stroke end, delivering smooth and safe deceleration

  • Designed for long-stroke stability
    Engineered to withstand bending (buckling) loads for extended strokes—ensuring superior safety

  • Robust, marine-grade finish
    Piston rod double-chromed with standard marine protection—ideal for aggressive environments

  • Versatile flange mounting
    Front (EF), bottom (FF), or pedestal flange (SF) mounting options suit a variety of industrial setups Wide temperature tolerance
    Operates reliably from –50 °C (with heating pad option) up to +60 °C
