130903000088A008 Air Suspension Damping Assembly Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 130903000088A008 air suspension shock absorption assembly is a core shock absorption component for the original equipment manufacturer (OEM) cab. It is compatible with the suspension shock absorption system of various engineering machinery cabs. Its core functions are vibration filtering, bump buffering, and attitude balance. It also features air suspension flexible shock absorption, adaptive damping, sealing and leak prevention, and quiet vibration resistance. It is suitable for strong vibration scenarios such as mines and construction sites, effectively filtering various vibrations, suppressing shaking and abnormal noises, and alleviating driver fatigue during long-term operation.
This product is a SANY original equipment assembly, precisely matched with SANY, XCMG, Caterpillar and other series of construction machinery, and compatible with loaders, excavators and other models. It adopts one-piece airtight die casting and multi-layer airbag composite molding process, and accurately connects to the original installation position and air circuit interface. It can be quickly installed without complicated debugging. It is airtight and stable, and is not afraid of dust, oil and dirt, high and low temperature. It solves the pain points of traditional mechanical shock absorption that are too stiff, uneven and easy to age.
As a core “flexible buffer component” in the cab, this product relies on an air suspension mechanical structure to replace traditional rigid shock absorbers. It can adaptively adjust its stiffness according to the load and road conditions, taking into account both support stability and ride softness, reducing resonance noise, reducing component wear, and making maintenance convenient and lifespan longer. It is a high-quality original spare part for shock absorber component repair and replacement, and bulk stocking.
