330103946 Screw XCMG XDE130 Electric driving dump truck spare parts

This screw solves the pain points of traditional screws, such as easy stripping, insufficient strength, poor wear resistance, and easy corrosion. It is compatible with the fastening and transmission mounting positions of multiple XCMG models and is suitable for harsh working conditions with high vibration, high dust, and high loads, such as in mines and construction sites. The product follows XCMG’s original factory standards. The 38CrMoAl alloy steel is rolled and nitrided for heat treatment, resulting in dense grains, excellent toughness, a nitriding layer depth of 0.3~0.6mm, a surface hardness >HV740, and thread precision that meets ISO standards. It has uniform stress distribution, withstands temperatures from -30℃ to +120℃, and is resistant to salt spray for ≥150 hours. It is impact-resistant and fatigue-resistant, with precise dimensions to fit the original mounting position. The thread has strong adaptability, allowing for direct screw-on installation. It is convenient, secure, and can be directly replaced. It effectively resists the attenuation of equipment vibration torque, prevents stripping and breakage, and meets the harsh outdoor use requirements of construction machinery.
