Product Number: HRS103BH
The HRS103BH is a hollow rubber spring rated at 500 kg nominal static load for use as a primary suspension spring, making it well suited to mainstream general-machinery mounting and moderate-load vehicle applications where progressive stiffness and high fatigue life are required without the maintenance demands of a metal coil spring. Where metal springs transmit vibration and offer no inherent damping, this rubber-to-metal bonded construction absorbs energy throughout the compression stroke, protecting surrounding structures and improving operator comfort across its working life. The spring delivers increased damping compared with steel coil equivalents and a progressive stiffness characteristic that stiffens naturally as deflection increases, a property particularly valuable in bump-stop and secondary assister roles. Rubber-to-metal bonded construction ensures consistent load transfer between the elastomer and the mounting hardware, and the maintenance-free design removes the need for lubrication or periodic adjustment in service. Loaded as a continuous assister spring, the HRS103BH accepts up to 1,520 kg static load; in bump or shock absorber duty it handles up to 2,270 kg, with a maximum deflection of 41 mm at that peak load. This load and deflection envelope makes it appropriate across construction and off-highway equipment, commercial and agricultural vehicles, trailers, marine installations, and power-generation plant. The spring may be loaded in shear, compression, or a combination of both depending on the mounting geometry of the application. This spring is the sole size in its immediate product group.

A. The HRS103BH has a nominal static load rating of 500 kg when used as a primary suspension spring. In continuous assister spring duty, it accepts up to 1,520 kg static load. As a bump or shock absorber, it handles a maximum load of 2,270 kg.
A. At its maximum load of 2,270 kg in bump or shock absorber duty, the HRS103BH deflects up to 41 mm. The progressive stiffness characteristic means deflection increases more gradually at lower loads before the spring stiffens under peak conditions.
A. The HRS103BH can function as a primary sole suspension spring, as a secondary assister spring alongside an existing spring system, or as a buffer and bump-stop shock absorber. The mounting geometry determines whether the spring is loaded in compression, shear, or a combination of both.
A. The spring is used across commercial and off-road vehicles, trailers, agricultural equipment, construction and off-highway machinery, marine installations, and power-generation plant — wherever progressive stiffness, energy damping, and a maintenance-free service life are required.
A. Unlike a metal coil spring, a hollow rubber spring provides inherent damping to absorb vibration energy rather than transmitting it. Its progressive stiffness characteristic stiffens naturally as load increases, and the rubber-to-metal bonded construction is maintenance free, requiring no lubrication or periodic adjustment.
A. Yes. Stainless steel metalwork, oil-resistant rubber compounds, and high-temperature rubber compounds are available on request, as are additional and custom sizes beyond the standard range.
A. Related variants for different load and size requirements include HRS103B/1, HRS140120, HRS1525H, HRS1525M, HRS155150, HRS170H, HRS5556, and HRS110180.
