380906164 XCMG GR2605 motor grader upper bushing

380906164 is a dedicated upper bushing for the XCMG GR2605 grader. It’s a wear-resistant bushing used in the hinge, steering, and suspension components. High in hardness, wear-resistant, and impact-resistant, it reduces wear when used with pins. It’s a direct fit to original factory dimensions.

Core Functions and Roles

Installed between the pin and the hinge seat, it reduces direct friction between the pin and the body, lowering wear and extending the service life of critical components such as the steering and suspension.

Made of wear-resistant alloy material, it resists pressure, impact, and deformation, adapting to the harsh working conditions of graders under heavy loads, bumps, and high impacts.

The inner and outer diameters and length strictly adhere to the original factory design, perfectly matching the 380906183 steering pin and other pins, with reasonable clearance for flexible and precise steering.
