advantages

Made of high-quality bearing steel with overall heat treatment, featuring high hardness and strong wear resistance, which effectively reduces component wear during long-term high-speed rotation.
Precision machining and strict tolerance control, ensuring excellent fitting accuracy, maintaining stable rotation coaxiality and avoiding transmission jitter and abnormal noise.
Excellent dynamic load resistance and fatigue resistance, adapting to frequent torque changes and impact loads of roller compaction operation, not easy to fail or deform.
Optimized internal rolling structure with low friction loss, effectively improving transmission efficiency and reducing equipment operating energy consumption.
Good sealing and environmental adaptability, resisting dust and muddy water erosion, avoiding early failure caused by impurity invasion.

maintenance & replacement tips

Regularly check the lubrication state of the main bearing to ensure sufficient and clean lubricating oil, avoid dry friction and abrasive wear.
Pay attention to abnormal noise, jitter and power attenuation during equipment operation to judge bearing working state in time.
Keep the internal transmission cavity clean to prevent impurities from entering the bearing and causing accelerated wear and pitting.
Avoid long-term overload operation and sudden impact torque to prevent bearing deformation and structural damage.
Use original 860508544 main bearing to ensure stable transmission operation and long-term working reliability of the roller.
