– Product Model: 329900300
– Product Name: Thickened Large Washer (Special for XCMG Construction Machinery, Pressure-bearing and Protective Type)
– Material Specifications: High-quality carbon steel, galvanized for corrosion protection, conforming to XCMG original factory standards and GB/T 5287-2002 national standard.
– Structure: Precision stamping, extra-large flat washer structure, smooth and burr-free surface, suitable for matching high-strength bolts of corresponding specifications.
This thickened gasket addresses the shortcomings of traditional gaskets, such as insufficient thickness, easy deformation, poor pressure resistance, and weak corrosion resistance. It is compatible with heavy-duty connection parts in various XCMG models and suitable for harsh working conditions such as construction sites and mines. The product complies with XCMG and national standards, using carbon steel that has been hardened and reinforced, with a thickness ≥3mm. It is galvanized for salt spray resistance ≥800 hours, withstands temperatures from -40℃ to 120℃, has a smooth, burr-free surface, and is compatible with corresponding bolt specifications. Installation is convenient and it can be directly replaced, effectively distributing bolt pressure, preventing damage to the substrate, and ensuring connection safety.
