805238372 Nut XCMG XDE130 Electric driving dump truck spare parts

The 805238372 nut addresses the pain points of traditional nuts, such as easy stripping and chipping, loosening due to vibration, softening at high temperatures, weak corrosion resistance, and poor engagement. It is widely used in core connection parts of XCMG construction machinery, compatible with excavators, cranes, mining trucks, and other equipment, serving as a key fastener for equipment maintenance and maintenance. This product adheres to XCMG’s original factory standards, using 40Cr high-strength alloy material, and undergoes tempering heat treatment and Dacromet anti-corrosion treatment. It integrates a Spilock wedge-shaped anti-loosening thread structure and is manufactured through cold heading, precision thread rolling, and post-weld flaw detection processes. Suitable for complex working conditions such as strong vibrations in mines, dust erosion, and high and low temperatures, it achieves a “the more vibration, the tighter the lock” effect without the need for additional locking components, preventing loosening and extending the life of the fastening system. In terms of performance, it has a strength grade of 8.8, a hardness of HV220-280, a thread accuracy of ISO 4H, no white rust after 48 hours of salt spray testing, is suitable for environments from -30℃ to 300℃, is resistant to creep and fatigue, conforms to the original XCMG bolt installation specifications, is easy and secure to install, can be reused, and has a significant effect on overcoming the problem of stripping in soft materials.
