130903000088A009 Air Spring Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 130903000088A009 air spring is a core elastic component of the cab, customized by the original manufacturer. It is compatible with the shock absorption system of various engineering machinery cabs. Its core functions are vibration buffering, elastic support, and posture compensation. It also features flexible shock absorption, airtight sealing, and tensile and tear resistance. It is suitable for strong vibration scenarios such as mines and construction sites, effectively buffering various bumps and impacts, helping to stabilize the cab posture, reducing vibration transmission, and alleviating driver fatigue during long-term operation.
As the core “elastic buffer unit” of the vibration damping system in the cab of construction machinery, this product relies on the principle of air elasticity to replace the traditional metal spring, flexibly buffering vibration and impact. It can be used with the shock absorption assembly to achieve adaptive adjustment, taking into account both support rigidity and buffer softness, reducing cab resonance, extending the overall life of the shock absorption system, and is easy to maintain. It is a high-quality original part for air spring repair and replacement, and bulk stocking.
