XCMG XE2000 Bolt (329901408): The Core Guarantee for Fastening Components in Mining Excavators

In the high-intensity working environment of mines, the tightness of connections for key components such as the excavator chassis and working devices directly determines the operational safety and service life of the equipment. XCMG XE2000 excavator-specific bolts (part number: 329901408), as the “fastening key” for core connecting components, with their customized adaptability design and superior anti-loosening performance, provide a solid connection defense for the continuous and stable operation of the XE2000 mining excavator, earning the trust of mining customers worldwide.

1. Customized adaptation for XE2000, ensuring precise and error-free connection.

The XE2000 mining excavator has an operating weight of 192,000 kg. During operation, its components withstand loads of hundreds of tons and high-frequency vibrations, placing stringent requirements on the dimensional accuracy and compatibility of the bolts. The 329901408 bolt was specifically developed based on the XE2000’s component connection parameters, achieving a thread precision of 6g and a pitch error controlled within ±0.02mm. The bolt length and diameter perfectly match the original factory mounting holes, allowing for direct and seamless replacement. After assembly, it fits tightly against the connecting surface, ensuring a coordinated tightening effect with the nut and preventing connection play caused by mismatches. This reduces component vibration and wear at the source, ensuring the coordinated operation of all equipment systems.

II. High-strength material + anti-loosening process, resulting in outstanding fastening performance.

In mining operations, continuous vibration, impact, and alternating high and low temperatures can easily cause ordinary bolts to loosen or break. Bolt 329901408 is made of 42CrMo high-strength alloy steel, which, after tempering heat treatment, achieves a hardness of HRC30-35, a tensile strength exceeding 1000MPa, and a yield strength exceeding 900MPa. The surface is coated with Dacromet anti-corrosion coating, with a salt spray test duration exceeding 500 hours, resisting corrosion from mining dust and humid environments. Simultaneously, it employs an anti-loosening pressure point process, enhancing vibration resistance through structural self-locking, maintaining a stable and tight state even under high-frequency vibration conditions. Its service life is 2.5 times longer than ordinary bolts, significantly reducing the risk of equipment downtime due to bolt failure.

III. International quality certification, adaptable to complex working conditions worldwide.

The 329901408 bolt is manufactured in accordance with the ISO9001 quality system and EU CE standards. It has passed SGS’s specialized testing for shear resistance, fatigue resistance, and corrosion resistance, meeting global mining operation requirements. Leveraging XCMG’s global R&D system, this bolt underwent testing during the design phase, simulating harsh conditions in various mining areas such as Australian iron ore mines, Congo (DRC) copper mines, and Chilean lithium mines. This ensures stable fastening performance in extreme environments ranging from -30°C to 50°C and high dust levels. Currently, it has been exported to over 20 countries along with the XE2000 excavator, providing reliable connections for key components in global mining equipment.
