XCMG XE2000 Excavator Piston Pin (Part No. 800169116): The Precision Connecting Core for Power Conversion

The XCMG XE2000 mining excavator, with its 192,000kg operating weight, 810kW imported engine, and 10-14m³ large bucket capacity, continuously delivers powerful output in heavy-duty mining operations worldwide. The piston pin (part no. 800169116), as a key transmission component connecting the piston and connecting rod, is the “power hub” that transmits the explosive force of the piston’s reciprocating motion to the crankshaft, directly affecting the engine’s power conversion efficiency and operational stability.

This piston pin is precision-rolled from high-strength alloy carburized steel, possessing excellent comprehensive mechanical properties. Through overall carburizing and quenching treatment, the surface hardness reaches 58-62HRC, while the core hardness remains at 30-35HRC, ensuring both high surface wear resistance and good impact toughness. Facing thousands of reciprocating motions per minute and severe impact loads within the engine cylinder, it effectively resists fatigue wear and deformation, preventing power interruption due to piston pin failure and providing a reliable connection guarantee for the engine’s continuous and efficient operation.

In terms of design, it was specifically developed based on the structural parameters of the XE2000 engine piston and connecting rod. The outer diameter accuracy, length dimensions, and fit clearance have been optimized through multiple rounds of dynamic simulation. It adopts a hollow cylindrical structure design, reducing its weight while increasing bending strength, with weight deviation controlled within 3g to ensure inertial balance during reciprocating motion. The outer cylindrical surface undergoes ultra-precision grinding, with a roughness controlled within 0.08μm, forming a highly efficient lubricated friction pair with the piston pin hole, reducing power transmission loss.

Relying on XCMG’s advanced manufacturing processes, this piston pin undergoes rigorous precision machining and quality testing. High-precision grinding using a centerless grinder ensures that the outer diameter tolerance is controlled within 0.002mm and the cylindricity error is ≤0.001mm, guaranteeing a perfect fit with the piston and connecting rod. The inner bore is honed to improve lubricant retention and enhance lubrication. Each piston pin undergoes 100% magnetic particle testing, eddy current testing, and full dimensional inspection to eliminate potential defects such as internal cracks and folds.

The performance of the piston pin directly affects the engine’s power output and fuel economy. During the engine’s working cycle, it precisely transmits the piston’s explosive force, ensuring efficient conversion of power into crankshaft rotational kinetic energy, enabling the XE2000 excavator to output stronger torque during heavy-duty digging. Excellent wear resistance reduces abnormal wear on the piston and connecting rod, extending the engine overhaul cycle by more than 30%. Precise fit clearances and lubrication design reduce friction loss, contributing to a 5-8% reduction in engine fuel consumption.

Choosing XCMG XE2000 excavator piston pins (part number 800169116) not only ensures you receive a high-quality transmission component that is precisely matched, durable, and reliable, but also allows you to leverage XCMG’s global service network to enjoy timely parts supply and professional technical support. Let this precision connecting core of power conversion solidify the power transmission link for your mining equipment’s engine, ensuring continuous and efficient production.
