860149576 sleeve pipe XCMG XE2000 excavator spare parts

XCMG XE2000 Excavator Sleeve (Part No. 860149576): Protective support to ensure the safety of pipelines and cables.

As a key protective component for the hydraulic pipelines and electrical cables of the XCMG XE2000 excavator, the sleeve with part number 860149576 is specially designed for complex working conditions such as the equipment chassis and boom connection. Its core function is to isolate the pipeline cables from the friction of metal parts and resist external impacts. It is suitable for critical lines such as hydraulic oil pipes and sensor cables. It is a “protective armor” that prevents pipeline wear and leakage, cable damage and short circuits in harsh working scenarios such as mining and infrastructure construction, and ensures the overall safe operation of the equipment.

Original factory precise fit, installation without deviation

Manufactured strictly according to the original layout parameters of the XCMG XE2000 excavator, the inner diameter (φ25mm), outer diameter (φ32mm), and length (80mm) perfectly match the dimensions of the pipeline cables and the reserved installation space. The chamfer angle at both ends (15°) conforms to the component assembly tolerance. After installation, there is no interference with the surrounding structure, and it can be directly embedded into the preset installation slot without additional grinding or adjustment. A chassis maintenance case of an XE2000 fleet shows that after replacing the non-standard sleeve with this original sleeve, the pipeline assembly qualification rate increased from 78% to 100%, avoiding pipeline bending and deformation caused by dimensional deviations, improving assembly efficiency by 50%, and significantly improving the regularity of the pipeline layout.

Wear-resistant and impact-resistant material, durable and resistant to damage

Made of high-strength nylon 66 (PA66) reinforced with glass fiber, and treated with low-temperature toughness modification, this casing achieves a Rockwell hardness of R110 and a tensile strength exceeding 80MPa. It can withstand friction from metal parts (friction coefficient ≤0.15) and impact from stones (impact strength ≥60kJ/m²). It exhibits excellent chemical corrosion resistance, remaining crack-free and non-swelling even after prolonged contact with hydraulic oil, coolant, and mud. Its temperature resistance ranges from -40℃ to 120℃, remaining non-brittle at low temperatures and non-deformable during high-temperature operation. Actual test data shows that the average mean time between failures (MTBF) exceeds 8000 hours, four times that of ordinary polyethylene casings. Under an average of 12 hours of high-intensity operation per day, it can be stably used for over 48 months, reducing downtime losses due to frequent replacements.

Dual protection function, reducing costs and increasing efficiency

On the one hand, its high-strength structure isolates the pipeline cables from direct contact with the metal support, avoiding pipe wall thinning and cable insulation damage caused by long-term friction; on the other hand, the smooth inner wall of the sleeve (roughness ≤ Ra0.8μm) reduces wear during pipeline vibration and provides a certain buffering effect, reducing impact damage to the pipeline. In an open-pit mine project in Inner Mongolia, XE2000 excavators equipped with this sleeve experienced a 90% reduction in hydraulic pipeline wear, a decrease in cable breakage from 3 incidents per month to 0 incidents, annual savings of over 18,000 yuan in pipeline replacement costs, and avoidance of over 30,000 yuan in electrical system maintenance costs due to cable short circuits. The equipment’s continuous operation rate also increased to 95%.

Easy to install, cost-effective

No special fixing tools are required; the snap-on design allows for direct engagement at the installation position. The sleeve surface is clearly marked with the part number and compatible pipeline specifications, facilitating quick model identification and accurate matching by maintenance personnel. Each sleeve weighs only 28g, making bulk storage and transportation convenient and resistant to damage from compression. In the long term, its high durability can reduce the frequency of sleeve purchases by 60%, and the improved protection avoids pipeline and cable maintenance costs, saving the XE2000 fleet over 50,000 RMB annually. Large fleets can enjoy XCMG’s original factory discounts for bulk purchases, further reducing overall operation and maintenance costs.
