805238372 Nut XCMG XDE130 Electric driving dump truck spare parts

The 805238372 nut addresses the pain points of traditional nuts, such as insecure tightening, easy stripping, poor fatigue resistance, and insufficient corrosion resistance. It is widely used in extreme heavy-load and high-vibration operating environments such as mining and infrastructure, and is a core component for equipment maintenance. The product uses XCMG’s special 40Cr high-strength alloy, which has excellent hardenability and significantly improved strength after heat treatment. The surface is treated with Dacromet corrosion protection and manufactured through multiple processes including cold forging, hot forging, precision thread rolling, and high-temperature heat treatment. It is suitable for high-frequency vibration and dusty operating conditions, perfectly compatible with original equipment, and meets XCMG’s digital transformation requirements for its supply chain.
