**Standard Conditions for Sealed Storage of SKF Bearings**

*Source: Bearing Network | Time: March 27, 2014*
Proper storage is essential to maintaining the performance and longevity of SKF bearings. When stored in a sealed environment, SKF bearings must meet specific hygiene and condition standards to prevent degradation. This includes ensuring that the sealing materials—often made from natural or synthetic rubber—are protected from environmental factors that could affect their integrity.
The storage guidelines for SKF bearings are aligned with international standards such as ISO 2230:1973 and DIN 7716. Additionally, for aerospace applications, the requirements outlined in DIN 9088 should also be followed. These standards provide detailed instructions on how to store elastomeric products safely and effectively.
For long-term storage, it's important to maintain proper storage equipment and environmental conditions. Even for short-term storage (within six months), such as during production and delivery, these standards still apply. While temperature control may not be strictly required, the appearance and functionality of the bearing must remain unaffected.
Improper storage conditions can lead to significant changes in the physical properties of rubber-based seals. This may result in reduced service life, hardening or softening of the material, permanent deformation, surface cracking, or Other forms of damage that render the bearing unusable. Factors such as exposure to oxygen, ozone, heat, light, moisture, solvents, and mechanical stress can all contribute to these issues.
However, when stored correctly, elastomeric components can retain their original properties even after years of storage. This makes proper storage a critical factor in ensuring the reliability and performance of SKF bearings.
In addition to technical considerations, hygiene plays an important role in the storage process. Clean and controlled environments help prevent contamination, which can negatively impact both the bearing’s performance and the machinery it supports.
