860146861 P22326 Spherical Roller Bearing For XCMG Excavator XE490DK

This is a genuine XCMG original accessory, tailor-made for XCMG XE490DK excavators and produced in strict accordance with XCMG's official manufacturing standards. Every parameter, from material selection to processing precision, is consistent with the parts installed on new XE490DK machines, ensuring zero adaptation issues during replacement. Unlike third-party substitutes, it fully inherits XCMG's quality genes, eliminating risks of mismatches or performance gaps.

Heavy-Duty Load Capacity: Boasts a basic dynamic load rating (Cr) of 722kN and static load rating (Cor) of 1140kN, making it capable of handling the intense radial and axial forces generated during heavy excavation, lifting, and rotation tasks. Even in long-hour continuous operations, it maintains stable performance without overload-related wear.​

Self-Aligning: Designed to accommodate angular misalignments of 0.5°-2°, a common issue caused by shaft deflection or component wear in XE490DK's high-load working scenarios. This feature reduces stress on the excavator's transmission parts, preventing premature damage and extending the overall service life of the machine.​

OEM-Grade Material: Crafted from GCr15 high-carbon chromium bearing steel, the same material used in XCMG's original bearings, with a hardness of HRC 60-64 after specialized heat treatment. This material combination ensures excellent wear resistance and toughness, letting the bearing withstand sudden impacts and strong vibrations in construction or mining sites.
