Contaminants, such as dust, dirt, metal shavings and moisture, are one of the main causes of insert bearing failure. When these contaminants enter the bearing, they can cause the following problems:
Increased friction: When contaminants enter the bearing raceway, they increase the friction between the rolling element and the raceway, causing the working conditions inside the bearing to deteriorate, thus accelerating wear.
Lubricant degradation: Contaminants can mix into the lubricant and reduce its lubrication properties. For example, water can emulsify the grease, resulting in poor lubrication; metal shavings may accelerate the oxidation of the grease and shorten its service life.
Corrosion: The infiltration of water and chemicals may cause corrosion on the bearing surface, which in turn affects the finish and precision of the bearing. Corrosion can cause pitting on the rolling element surface, increase friction and generate more wear particles, forming a vicious cycle.
By cleaning the bearing regularly, these contaminants can be effectively removed, preventing them from causing further damage to the bearing and ensuring that the lubricant works in good condition.
Extending the service life of the bearing
The service life of the bearing is usually determined by its operating conditions and maintenance level. Regular cleaning of bearings can significantly extend their service life in the following ways:
Reduced wear: Cleaning can remove dirt and residue from the bearing surface, maintain the smoothness of the raceways and rolling elements, thereby reducing friction and wear.
Optimized lubrication: After cleaning, the reapplied lubricant can work better in a contaminant-free environment, forming a stable lubricating film to protect the bearing from metal contact wear.
Prevent overheating: Dirt and old lubricant accumulated inside the bearing will hinder the dissipation of heat, causing the bearing to overheat. By cleaning, you can ensure that the bearing maintains the appropriate temperature during operation, thereby preventing bearing damage caused by overheating.
