805006286 Bolt XCMG XDE130 Electric driving dump truck spare parts

805006286 bolts address the pain points of traditional bolts, such as easy stripping, vibration loosening, high-temperature softening, weak corrosion resistance, and fatigue fracture. They are widely used in core connection parts of XCMG construction machinery, such as suspension systems, slewing bearings, and gearboxes. They are compatible with various series of equipment, including loaders, excavators, cranes, and mining trucks, and are key high-strength fasteners for the maintenance and matching of equipment fastening systems. This product adheres to XCMG’s original factory standards, using 40CrNiMoA high-strength alloy material. It undergoes heat treatment (quenching and tempering) and Dacromet corrosion protection, integrating a Spirax 30° wedge-shaped anti-loosening thread structure. By altering the thread’s stress pattern, the anti-loosening friction is three times that of ordinary threads, effectively offsetting the risk of loosening caused by vibration. Manufactured through cold heading, precision thread rolling, and post-weld flaw detection, it is suitable for complex working conditions such as strong earthquakes in mines, dust erosion, and high and low temperatures. It achieves a “the more vibration, the tighter it locks” effect, preventing loosening and failure. Simultaneously, the load is evenly distributed, eliminating the fatigue fracture risk caused by concentrated stress in traditional threads, ensuring a stable connection of core components. In terms of performance, it has a strength grade of 10.9, a tensile strength of ≥940MPa, a thread accuracy of ISO 4H, and no white rust after 72 hours of salt spray testing. It is suitable for environments ranging from -35℃ to 320℃, and has excellent creep and fatigue resistance. It has been verified by the GB/T 10431-1989 transverse vibration test and can maintain a locked state under high-frequency vibration. It conforms to the original XCMG bolt installation specifications, making installation convenient and secure. It can achieve reliable locking without the need for additional anti-loosening washers, and can be repeatedly installed and disassembled while maintaining its locking performance. Long-term use can significantly reduce maintenance costs.
