800553777 XCMG GR2605 motor grader joint bearing

Core Product Advantages

Designed specifically for the XCMG GR2605 motor grader, its inner and outer diameters and thickness are machined strictly to original factory dimensions, ensuring a perfect match with pins, connecting rods, and mounting bases. No adjustments are needed upon installation; it’s a direct replacement. Utilizing a self-lubricating composite structure, it offers flexible rotation and low frictional resistance, reducing daily lubrication maintenance and adapting to long-term continuous heavy-duty operation. It can simultaneously withstand radial, axial, and combined loads, exhibiting outstanding resistance to eccentric loads, impacts, and vibrations, providing strong stability under high-load conditions such as in mining and construction sites.

The inner and outer rings are made of high-strength wear-resistant alloy steel and undergo precision heat treatment, resulting in high surface hardness and excellent wear resistance, effectively reducing wear and extending service life. The compact and robust structure effectively improves issues such as looseness, abnormal noise, and jamming at hinge points, significantly enhancing the mechanism’s motion precision and overall machine handling feel.
