380603779 XCMG GR2605 motor grader bushing

Core Product Advantages

Specifically designed for the articulation and rotation system of the XCMG GR2605 grader, its inner diameter, outer diameter, and length are manufactured strictly according to original factory standards, ensuring high precision matching with pins and mounting seats, preventing uneven wear and looseness during assembly.

Made of high-strength wear-resistant alloy material, it boasts outstanding resistance to pressure, impact, and vibration, resisting deformation and breakage even under heavy loads, high-frequency reciprocating motion, and conditions involving mud and sand. Its high surface finish ensures smooth contact with pins, effectively reducing frictional resistance, noise, and jamming, and protecting the journal and mounting hole from damage. Excellent wear-resistant and friction-reducing properties significantly extend the service life of articulated components, reducing maintenance frequency and costs. Suitable for harsh working conditions such as mines, roadbeds, airports, and municipal construction sites; easy to install, directly press-fits to replace the original bushing, quickly resolving issues such as large clearances, slow rotation, uneven wear, and abnormal noise.
