 Latest company case about What is the best way to preserve a bearing for storage?
  1. Maintain Cleanliness

    • Clean Before Storage: Ensure bearings are clean before storing. Remove any contaminants like dirt or old lubricant.
    • Protect from Contaminants: Store in a clean environment free from dust, moisture, chemicals, and other contaminants.
  2. Control Environmental Conditions

    • Temperature Control: Store in an area with stable temperatures between 5°C (41°F) and 25°C (77°F). Avoid extreme temperature fluctuations.
    • Humidity Control: Keep humidity levels below 60% to prevent corrosion. Use desiccants or climate-controlled storage if necessary.
  3. Proper Packaging

    • Original Packaging: Store in original packaging when possible, as it provides protective materials.
    • Sealed Containers: If not using original packaging, place bearings in sealed containers or plastic bags.
    • Corrosion Protection: Apply rust-preventive oils or coatings for long-term storage. Consider VCI (vapor corrosion inhibitor) packaging.
  4. Avoid Stress and Damage

    • Handle with Care: Handle gently to avoid damaging rolling elements or raceways. Do not stack heavy objects on bearings.
    • Support Properly: Support larger bearings properly to prevent deformation. Store cylindrical roller bearings horizontally.
  5. Regular Inspection

    • Periodic Checks: Inspect stored bearings periodically for damage or corrosion, especially for long-term storage.
    • Rotate Bearings: Rotate large bearings occasionally to prevent flat spots from developing.
  6. Documentation and Labeling

    • Keep Records: Maintain records of storage conditions and duration for each batch.
    • Label Clearly: Label bearings with type, size, manufacture date, and expected shelf life.
