XCMG XE2000 Excavator Connector (803405660): The Precision Connection Core of Power Transmission in Mining

In core mining regions worldwide, such as Indonesia, the Democratic Republic of Congo, and Brazil, the XCMG XE2000 mining excavator, with its ultra-large 12-cubic-meter bucket capacity and over 93% mobility, has become a mainstay of efficient mining operations. In the power transmission network of this “mining giant,” the connector with part number 803405660 acts as a “precision connection hub,” connecting various pipelines and core components. It is a key component ensuring the efficient and sealed transmission of hydraulic oil, coolant, and other media, providing a solid guarantee for the stable operation of the entire machine.

Original factory precision fit, seamless integration with the entire machine system

The XCMG XE2000 connector (803405660) was specifically developed by the XCMG R&D team to meet the piping layout and connection requirements of the XE2000 excavator, undergoing 3D modeling analysis and hundreds of real-machine tests. Its interface dimensional accuracy is controlled within ±0.02mm, and its thread specifications, sealing structure, and interface parameters perfectly match those of core components such as the hydraulic pump, main valve, and hose assemblies. Whether in static connections of high-pressure hydraulic lines or dynamic connections of moving parts such as the boom and stick, it achieves a tight, precise fit, completely eliminating installation difficulties or loose connections caused by dimensional deviations, creating a “zero-leakage” connection channel for the entire machine’s power transmission.

High-strength Material, Durable Guarantee Under Extreme Working Conditions

Forged from high-strength alloy structural steel and strengthened through a precise heat treatment process, the joint boasts a tensile strength exceeding 800MPa and a hardness of HRC35-40, exhibiting excellent pressure resistance and wear resistance. The joint surface undergoes multi-layer chrome plating, with uniform thickness and strong adhesion, effectively resisting oil, moisture, and dust corrosion in mining environments, increasing corrosion resistance by over 30%. Verified through extreme environment testing, it maintains stable structural performance even in temperature fluctuations ranging from -40℃ to 120℃ and high-frequency vibration environments, extending its service life by more than 2.5 times compared to ordinary joints, significantly reducing the risk of equipment downtime due to joint damage.

Superior Sealing Performance, Ensuring Efficient Media Transmission

The joint incorporates high-precision seals made of imported high-pressure resistant fluororubber, combined with a precise conical sealing structure design, achieving a sealing pressure of up to 400MPa, ensuring no media leakage under high-pressure operating environments. Its threads are machined using a precision rolling process, resulting in high tooth profile accuracy and a smooth surface. Combined with an anti-loosening design, it effectively prevents thread loosening caused by equipment vibration, ensuring long-term connection reliability. When the XE2000 excavator is operating at full load, it ensures that hydraulic oil and other media pass through with a transmission efficiency of over 99%, providing continuous power support for the powerful digging operation of the 12 cubic meter bucket and avoiding power loss and environmental pollution caused by leakage.

For mining companies pursuing efficient operations, the XCMG XE2000 connector (803405660) is not only a high-quality connecting component but also a “safety lock” ensuring smooth power transmission. Choosing original equipment manufacturer (OEM) parts means choosing reliability that perfectly matches the performance of the XE2000 excavator, providing a solid guarantee for efficient mining operations.
