Industry Guide: Standard Practices for Bearing Management to Extend Machinery Life

[Introduction] As the "heart" of the mechanical industry, the operating status of bearings directly affects equipment efficiency and lifespan. Statistics show that approximately 36% of premature bearing failures are caused by improper installation. This article provides a detailed analysis of standardized procedures from storage to operation.

1. Scientific Storage: Prevention is Better Than Cure
Bearings are precision components with high environmental requirements.
• Environment Control： 
Bearings should be stored in a dry, ventilated indoor environment with constant temperature. Relative humidity should be kept below 60%.
• Packaging： 
It is strictly forbidden to open the original packaging before installation. If the packaging is damaged, anti-rust oil must be reapplied and the bearing resealed.
• Placement：
Large bearings should be stored flat. Vertical placement is strictly prohibited to prevent ring deformation due to self-weight.

2. Preparation Before Installation: Ready for Success
Before formal installation, ensure that the working environment and components are in optimal condition.
• Cleanliness：
The installation area should be far from metal chips, dust, and moisture.
• Dimensional Check：
Use high-precision measuring tools to verify the tolerances of the shaft and housing. Ensure the shaft is free of bends and burrs.
• Tools Inventory：
Prepare professional induction heaters, brass bars, or specialized sleeve tools. Avoid direct hammering on the bearings.

3. Post-Installation Inspection: The Final Line of Defense
After installation, the bearing should not be operated at full load immediately. A rigorous inspection is mandatory.
• Rotation Check：
Rotate the components manually to confirm whether the rotation is smooth and free of abnormal resistance or noise.
• Lubrication Verification：
Ensure that the correct brand and quantity of grease or oil has been applied.
• Trial Run Monitoring：
After starting at low speed, monitor the bearing temperature. Under normal conditions, the temperature should rise gradually and stabilize.

Conclusion
Standardized maintenance and installation not only reduce maintenance costs for enterprises but also guarantee production safety.
