381200411 XCMG GR2605 motor grader upper hinge shaft

381200411 XCMG GR2605 motor grader upper hinge shaft

Core Product Advantages

Specifically designed for the XCMG GR2605 grader frame articulation system, the axle diameter, installation dimensions, and fit tolerances strictly adhere to original factory standards. It boasts high precision matching with the articulation frame, bushings, and bearings, ensuring a close fit and smooth rotation. Forged from high-strength alloy structural steel and subjected to tempering and quenching strengthening treatments, it exhibits excellent tensile, compressive, and impact resistance, remaining unbent, unbreakable, and wear-free under heavy-load steering conditions. The journal surface is precision ground and polished, resulting in high smoothness and wear resistance. The low resistance during mating with the copper bushing/copper sleeve effectively reduces abnormal noise, jamming, and uneven wear, extending the life of the articulation components. High rigidity, deformation resistance, and fatigue resistance make it suitable for harsh and bumpy operating environments such as mines, roadbeds, and construction sites, ensuring stable performance over long-term use. Easy installation and maintenance; it directly replaces the original hinge shaft, quickly resolving issues such as large articulation gaps, steering noise, excessive sway, and uneven wear.
