380903972 XCMG GR2605 motor grader pin

Core Product Advantages

Precision machining strictly according to original factory drawings, ensuring high accuracy in outer diameter, length, and tolerances. Reasonable clearances with bushings, spherical bearings, and mounting seats ensure smooth assembly without looseness or jamming. Made of high-strength alloy structural steel, and subjected to multiple heat treatment processes including tempering and quenching, resulting in excellent comprehensive mechanical properties. Strong tensile, compressive, and shear strength, making it resistant to bending and breakage under heavy loads. The pin surface undergoes high-precision grinding, achieving a high degree of smoothness and low friction coefficient, effectively reducing wear on bushings and bearings and extending the service life of the entire hinge mechanism. Excellent impact and vibration resistance, maintaining dimensional stability and structural strength even in harsh, high-vibration environments such as mines, construction sites, and roadbed construction, resulting in higher reliability. Surface anti-rust and anti-corrosion treatment, resisting oxidation, oil stains, and rust, suitable for long-term continuous outdoor operation; easy installation and disassembly, directly replacing original parts, significantly improving maintenance efficiency.
