380903663 XCMG GR2605 motor grader hydraulic cylinder mount

380903663 XCMG GR2605 motor grader hydraulic cylinder mount

Core Product Advantages

Specifically designed for the XCMG GR2605 grader’s working device and hydraulic system, the mounting hole spacing, shaft hole center height, and hinge positions are all machined strictly according to the original factory drawings, ensuring a perfect match with the cylinders, frame, and working device, eliminating the need for secondary adjustments during installation. Constructed from high-strength alloy cast steel or thick plate welded molding, it boasts excellent overall rigidity, bending, torsion, and impact resistance, remaining undeformed, crack-free, and stable even under complex working conditions such as heavy-duty leveling, slope trimming, and large-angle operations. Key stress areas are reinforced for uniform stress distribution, allowing it to withstand alternating loads generated by cylinder push-pull operations for extended periods, exhibiting excellent fatigue resistance and meeting the demands of high-intensity continuous construction. The shaft hole areas feature high precision and a smooth surface, with reasonable clearances with pins and bushings, ensuring smooth operation, effectively reducing abnormal noise, uneven wear, and jamming, and extending the service life of hinge components. The surface is treated with rust and corrosion prevention, exhibiting strong adhesion, resistance to oil and dust, and adaptability to harsh working conditions such as mining, roadbed, and airport construction. Installation is convenient, directly replacing the original cylinder seat, significantly improving maintenance efficiency.
