380903999 XCMG GR2605 motor grader pin

Core Product Advantages

Precision machining strictly according to original factory dimensions and tolerances, with standardized outer diameter, length, and fit accuracy. High compatibility with bushings, bearings, and mounting supports ensures smooth assembly, reasonable clearances, and prevents looseness or jamming; ready for immediate use after installation. Made of high-strength alloy structural steel and subjected to multiple heat treatment processes including tempering and quenching, resulting in excellent tensile, compressive, and shear strength. Resistant to bending and breakage under heavy loads, impacts, and continuous vibration, providing ample safety margin. The pin surface undergoes precision grinding and polishing, resulting in high smoothness and a low coefficient of friction, effectively reducing wear on mating parts, lowering the probability of abnormal noise and jamming, and extending the overall service life of the articulated mechanism. Excellent fatigue and impact resistance allows for stable operation under harsh conditions such as mining, roadbed, and airport construction, resisting wear and deformation for enhanced reliability. Rust and corrosion prevention treatment ensures oxidation resistance, oil resistance, and rust resistance, making it suitable for long-term continuous outdoor operation. Easy disassembly and assembly; directly replaces the original pin, significantly improving equipment maintenance efficiency.
