Engineered for heavy-duty service, the HRS540/1 is a Ø63mm hollow rubber spring rated to carry a nominal static suspension load of 500 kg, a maximum continuous assister load of 2,300 kg, and a peak bump or shock load of 3,400 kg, with a maximum deflection of 75 mm at full load. Where shock absorption and high-load restraint are the governing demands, this spring delivers the fatigue resistance and progressive stiffness characteristics that metal coil springs cannot match unaided. Hollow rubber springs of this type combine rubber-to-metal bonded construction with a progressive stiffness curve, meaning resistance increases as deflection builds, a property that makes them well suited to bump-stop and shock-absorber duties as well as primary suspension. Maintenance-free by design, they require no lubrication and resist the fatigue cycling that undermines conventional spring steel over time. The hollow geometry allows the spring to be loaded in compression, shear, or a combination of both, giving engineers flexibility in mounting orientation. At the heavier end of the load band, HRS540/1 is particularly suited to applications in commercial and off-road vehicle suspension, trailer chassis buffer duties, construction plant, and heavy agricultural equipment where impact loads are frequent and damping demands are high. It is equally applicable to power generation, marine, and industrial machinery installations where protecting surrounding structures and improving operator comfort under shock loading are priorities. The range also serves railway and mass transit, and military and defence sectors.

A. Used as a primary suspension spring, the HRS540/1 carries a nominal static load of 500 kg.
A. Yes — when configured as a secondary assister spring, the HRS540/1 supports a maximum continuous static load of 2,300 kg.
A. The HRS540/1 is rated to a maximum bump and shock load of 3,400 kg, making it suitable for heavy-duty buffer and bump-stop duties.
A. Deflection at maximum load is 75 mm.
A. The spring is used in vehicle suspension systems, commercial and off-road vehicles, trailers, construction equipment, and heavy agricultural machinery. It also serves power generation, marine, railway, and industrial applications where shock damping and high-load performance are required.
A. Progressive stiffness means resistance increases as the spring deflects. Under impact or overload, the spring becomes progressively stiffer rather than bottoming out abruptly, which protects surrounding structures and improves operator comfort.
A. Yes — stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request, as are additional custom sizes.
A. Yes — the range includes HRS100130, HRS10069, HRS110133H, HRS505H, HRS530, HRS535, HRS90125, and HRS9696, each with different load and deflection ratings to suit different applications.
A. In-stock orders placed before 14:30 Monday to Friday are usually dispatched the same day.
