Bearings are one of the most critical parts of the design and function of the machinery. Since they are often being run close to their designed operating limits, they must be in perfect condition before the assembly into the end product. Therefore, the correct storage of the bearing is of great importance. Here are some of the basic guidelines for the proper storage of your bearings.  

Packaging

Bearings cannot be kept in storage for unlimited periods of time, but they are protected against corrosion for several years if stored in their closed, original packaging. Keeping bearings in their original packaging is crucial until they are ready to be used. If the original packaging is damaged or needs to be replaced, use clean, airtight containers with desiccants to maintain a dry environment. 

Cleanliness 

Bearings must be stored in a clean environment to prevent contamination. Dust, dirt, and other foreign particles can cause significant damage to bearings, leading to increased wear and tear. Ensure the storage area is free from contaminants, and bearings should always be handled with clean gloves to avoid introducing any harmful substances. 

Environment Control

The storage environment plays a critical role in maintaining bearing quality. The ideal storage conditions include: 

• Temperature: Store bearings in a cool, stable temperature environment. Extreme temperatures, whether high or low, can affect the lubricants and materials in the bearings. Ideally, the storage temperature should be between 0°C and 25°C. 
• Humidity: High humidity levels can lead to condensation and rust. It is essential to keep the humidity levels low, preferably below 60%. Using desiccants and dehumidifiers can help control the humidity in the storage area. 
• Light: Bearings should be stored away from direct sunlight and UV light, which can degrade certain materials and lubricants over time.

Position and Orientation

Proper positioning of bearings during storage is vital. Bearings should be stored horizontally to distribute the load evenly and prevent deformation. Storing bearings vertically can cause brinelling or indentations in the raceways, leading to operational issues. 

Stock Rotation

If you have a large inventory of bearings, it is essential to rotate the stock to ensure that older bearings are used first. This practice, known as FIFO (First In, First Out), helps prevent bearings from sitting in storage for too long and potentially degrading over time. 

Inspection and Maintenance

Regular inspection of stored bearings is necessary to ensure they remain in good condition. Periodically check for signs of corrosion, contamination, or damage. If any issues are found, address them immediately to prevent further deterioration. 

Handling with Care

Bearings are precision components and should be handled with utmost care. Avoid dropping or striking bearings, as mechanical shocks can cause significant damage. Use appropriate lifting tools and equipment when moving heavy bearings to prevent accidental impacts.
