330101045 Bolt XCMG XDE130 Electric driving dump truck spare parts

The 330101045 bolt addresses the pain points of traditional bolts, such as easy breakage, vibration loosening, high-temperature softening, weak corrosion resistance, and thread stripping. It is widely used in core connection parts of XCMG construction machinery, including power take-offs and slewing bearings, and is compatible with various equipment such as loaders, excavators, and cranes. It is a key high-strength fastener for equipment fastening system maintenance and maintenance. This product adheres to XCMG’s original factory standards, using 45# high-strength carbon steel, and undergoes heat treatment (quenching and tempering) and Dacromet corrosion protection. It integrates a precision rolled thread structure and is manufactured through cold heading, thread grinding, and online flaw detection. It is suitable for complex working conditions such as strong earthquakes in mines, dust erosion, and high and low temperatures. It can effectively resist the effects of alternating loads, avoid fatigue fracture during low-speed operation, ensure the stable connection of core components, and prevent equipment failure caused by bolt failure. In terms of performance, it has a strength grade of 8.8, a tensile strength of ≥800MPa, a thread accuracy of ISO 4H, and no white rust after 48 hours of salt spray testing. It is suitable for environments ranging from -30℃ to 300℃, and has excellent creep and fatigue resistance. 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 components. The products in the same batch have high performance consistency and can directly replace original parts.
