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 suggestions for the proper storage of your bearings.
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. They should be stored horizontally in their original, unharmed and unopened packaging. Make sure you visually examine the packaging and return the bearing if there are any significant damage indications.
Bearings should be stored in a clean, dry, and low-humidity environment. Storage room humidity should not exceed 60%. Always avoid storing the bearings in sun-exposed places as well as placing the bearings against cold walls. There shouldn`t be any sudden or severe changes in the temperature which may cause condensation. The storage area should also be vibration-free.
Lubricant deteriorates over time as a result of aging, condensation, and separation of the oil and thickener. If sealed bearings are kept in the storeroom for a longer time, grease can solidify. After mounting such bearing will have a higher moment of friction. This should be taken into consideration.
If the bearings are stored for longer time periods, we advise that they are stored on shelves that are set higher than 30 cm at the recommended temperature of 20℃.
