800169159 main bearing XCMG XE2000 excavator spare parts

XCMG XE2000 Excavator Main Bearing (Part No. 800169159): The Wear-Resistant Support Core for Engine Operation

The XCMG XE2000 mining excavator, with its 192,000kg operating weight, 810kW imported engine, and 10-14m³ large bucket capacity, continuously delivers powerful performance in heavy-duty mining operations worldwide. The main bearing (part no. 800169159), as a key support component of the engine crankshaft, is crucial for ensuring the crankshaft’s high-speed and stable operation, directly impacting the reliability and service life of the entire machine’s power system.

This main bearing is precision-machined from high-quality high-carbon chromium bearing steel, combined with advanced alloy plating technology, possessing excellent wear resistance and load-bearing capacity. Facing the enormous radial loads and impact forces generated by the XE2000 engine crankshaft during operation, it forms a stable support structure, effectively dispersing stress and preventing bearing deformation or accelerated wear due to overload, providing long-lasting and reliable operation protection for the crankshaft. In terms of design, it was specifically developed based on the crankshaft journal parameters and operating conditions of the engine. The bearing’s inner diameter, width, and clearance have been precisely calibrated. An optimized raceway curve and roller arrangement design ensure perfect fit with the crankshaft journal, reducing the coefficient of friction and energy loss during operation. A precise sealing structure effectively prevents impurities in the lubricating oil from entering, protecting the internal raceways and rollers of the bearing and extending its service life.

Relying on XCMG’s advanced manufacturing processes, this main bearing undergoes rigorous precision testing and performance evaluation. The roller and raceway surfaces are ultra-precision ground and polished, with surface roughness controlled to an extremely low level, significantly reducing friction and wear. Stringent fatigue life tests ensure stable performance even under long-term, high-frequency operation, meeting the long-term operating requirements of heavy-duty mining operations.

The performance of the main bearing directly affects the engine’s operational stability and power output efficiency. Through stable support, it ensures the concentricity of the crankshaft during high-speed operation, reducing vibration and noise and improving engine smoothness. Its excellent lubrication and friction characteristics reduce mechanical wear, helping the engine convert more energy into effective power and improving fuel economy. Simultaneously, reduced wear lowers the risk of engine failure, extends overhaul intervals, and reduces equipment maintenance costs.

Choosing the XCMG XE2000 excavator main bearing (part number 800169159) not only provides you with a high-quality, wear-resistant, and reliable support component with strong load-bearing capacity, but also allows you to enjoy timely parts supply and professional technical support through XCMG’s global service network. This wear-resistant support core for engine operation builds a solid operational defense for your mining equipment’s power system, ensuring uninterrupted and efficient production.
