XCMG XE2000 Bolt M12×50 (805046636): The Precision Core for Fastening Components in Mining Excavators

In the high-intensity working environment of mines, the tightness of connections between 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 M12×50 bolts (part number: 805046636), as “precision fasteners” for connecting equipment components, with their customized specifications and superior anti-loosening performance, provide a solid connection defense for the stable operation of the XE2000 mining excavator, winning the trust of mining customers worldwide.

1. Customized fit for XE2000, ensuring precise and error-free fastening.

The XE2000 mining excavator has an operating weight of 192,000 kg, and its component connections must withstand heavy impacts and high-frequency vibrations, requiring stringent dimensional accuracy of the bolts. The 805046636 bolts are manufactured strictly according to the M12×50 standard specification, with a thread precision of 6g grade and a pitch error controlled within ±0.02mm. Their length and effective thread depth perfectly match the installation requirements of XE2000 components, allowing for seamless replacement of original bolts. After assembly, they tightly fit the nut and connecting hole, avoiding tightening gaps caused by dimensional deviations, ensuring the connection stability of core components such as the boom and stick, and reducing component wear caused by loosening.

II. High-strength material + anti-loosening process, maximizing durability.

In mining operations, bolts are subjected to alternating loads, vibrations, and coolant corrosion over long periods, making ordinary bolts prone to stripping or breakage. The 805046636 bolt is made of 35CrMo high-strength alloy steel, achieving a hardness of HRC28-32 after tempering heat treatment. It boasts a tensile strength exceeding 800MPa and a yield strength exceeding 650MPa. The surface is coated with Dacromet anti-corrosion coating, with a salt spray test duration exceeding 500 hours, resisting the erosion of the humid and dusty mining environment. It also incorporates an anti-loosening pressure point design, which, after tightening, enhances vibration resistance through structural self-locking, maintaining a stable preload even under high-frequency vibration conditions. Its service life is 2.5 times longer than ordinary M12 bolts, significantly reducing equipment maintenance costs.

III. International quality certification, compatible with mining areas worldwide.

The 805046636 bolt is manufactured in accordance with the ISO9001 quality system and EU CE standards. It has passed SGS’s specialized tests for tensile strength, corrosion resistance, and resistance to loosening, ensuring its quality meets global mining operation requirements. Leveraging XCMG’s global R&D system, this bolt underwent testing during the design phase, simulating harsh working conditions in various mining areas such as Australian iron ore mines and Congo (DRC) copper mines. This ensures stable fastening performance in environments ranging from -30℃ to 50℃ and high dust levels. Currently, it has been exported to over 20 countries with the XE2000 excavator, providing reliable fastening guarantees for component connections in mining equipment worldwide.
