150901020081B004 Buffer sleeve Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 150901020081B004 buffer sleeve is a core buffer and protection component for hydraulic cylinders. It is mainly used for buffering and decelerating at the end of the cylinder stroke, absorbing the impact inertia of operation, preventing hard collisions between the piston rod, end cap, and cylinder body, and eliminating abnormal noise and vibration of the equipment. The product is made of high-toughness and wear-resistant material, which is pressure-resistant, impact-resistant, fatigue-resistant, and not easily damaged. It is suitable for high-frequency heavy-load operation scenarios such as earthmoving and mining.
This original factory-fitted buffer sleeve is precisely sized and fits snugly, perfectly adapting to the internal structure of the hydraulic cylinder, ensuring smooth and seamless operation. It reduces the impact of cylinder start-up and shutdown, alleviates instantaneous high-pressure loads, reduces wear on seals and metal components, and extends the cylinder’s lifespan. Old buffer sleeves are prone to hardening, wear, cracking, and failure, causing cylinder overshooting, vibration, component damage, and equipment malfunctions. This product is an original factory standard part, supporting in-situ non-destructive replacement, suitable for equipment maintenance, overhauls, and bulk stocking, quickly restoring the hydraulic cylinder’s buffering and protective capabilities, and reducing operating costs.
