800168957 roller bearing XCMG XE2000 excavator spare parts

XCMG XE2000 excavator roller bearing (part number 800168957): wear-resistant and load-bearing, ensuring stable transmission.

As a core supporting component of the transmission system and slewing mechanism of the XCMG XE2000 excavator, the roller bearing with part number 800168957 plays a crucial role in bearing heavy radial loads and reducing component friction. It is suitable for high-frequency stress parts such as slewing bearings and travel drive axles. It is a “key hub” in high-intensity operation scenarios such as mining and infrastructure construction, ensuring smooth equipment transmission and preventing component wear.

Original factory precise fit, seamless installation

Manufactured strictly according to the original design standards of XCMG XE2000 excavators, the inner diameter, outer diameter, and width dimensions match the component mounting positions with an accuracy of ±0.01mm. The rolling element and raceway fit clearance is controlled within 0.005-0.01mm, ensuring a tight fit with the shaft and bearing housing after installation, with no play or misalignment. A maintenance case of the slewing mechanism in an XE2000 fleet shows that after replacing the aftermarket parts with this original factory roller bearing, the bearing assembly deviation rate decreased by 98%, and the coaxiality of the slewing mechanism improved to within 0.02mm, avoiding abnormal noise and jamming problems caused by misalignment.

Highly wear-resistant material, strong load-bearing and durable

Made from GCr15SiMn high-carbon chromium bearing steel through integral quenching, the rolling elements achieve a surface hardness of HRC62-65 and a contact fatigue life exceeding 1200 hours. The cage is made of high-quality brass with a tensile strength of 300MPa, capable of withstanding radial loads (≤50kN) and instantaneous impact loads (≤80kN). Internally filled with high-temperature grease, it has a temperature resistance of up to 150℃ and stable lubrication performance within a temperature range of -40℃ to 120℃. Actual test data shows that its service life is 3.8 times that of ordinary roller bearings, and it can be stably used for more than 36 months under 12 hours of high-intensity operation per day, reducing downtime losses caused by frequent replacements.

Stable transmission and reduced wear

Through precision grinding, the raceway surface roughness is ≤0.8μm, and the rolling element roundness error is ≤0.002mm, effectively reducing the coefficient of friction (≤0.0015) and achieving a transmission efficiency of over 99.5%. Simultaneously, the bearing sealing structure employs a double-lip rubber seal ring, achieving an IP65 dustproof and waterproof rating, preventing dust and mud intrusion and avoiding internal corrosion. In a rainy mining project in Yunnan, an XE2000 excavator equipped with this roller bearing experienced no abnormal wear on its drive axle after 24 months of continuous operation, a 75% reduction in transmission system failure rate, and an average annual reduction in maintenance costs exceeding 32,000 yuan.

Easy to install, cost-effective

No specialized pressing equipment is required; assembly can be completed using standard bearing installation tools and a heating kit. The bearing surface is clearly marked with the part number, specifications, and installation direction, facilitating quick identification and standardized operation by maintenance personnel, reducing the risk of incorrect installation. From a long-term cost perspective, its high durability and low failure rate can reduce bearing procurement and replacement expenses for the XE2000 fleet by 45%. When large fleets are used in bulk, they can enjoy XCMG’s original bulk discount, making the cost advantage even more significant.
