Storage of bearings
The storage of bearings is very important to their efficient operation. The correct stored environment will help to maintain the highest performance and extend the operating life of the bearings. Bearing storage must consider temperature, moisture, cleanliness and other factors.
Temperature
Bearings should not be exposed to temperatures greater than 140°F for any time period. At temperatures of 140°F and beyond, the structural integrity of the bearing is compromised and permanent damage may occur. If a bearing must be stored for extended periods at temperatures above 120°F, it should be allowed to cool to room temperature before being placed into service. High temperatures can cause deterioration of lubricants and other components used on or near the bearing.
Moisture
The prevention of moisture is key to successful bearing storage. If moisture isn’t controlled, rust and corrosion can form within the bearing components and damage its parts. Any additional rust or water molecules can cause increased friction and hazardous operation. Bearings should always be stored indoors, preferably in a climate-controlled setting to ensure temperatures remain below 140°F and that moisture isn’t an issue.
Cleanliness
It is important for bearings to be stored in a completely clean setting. Contamination due to dust, dirt, or other foreign materials can cause damage to the bearing, resulting in premature failure and reduced service life. Bearings should be stored in a controlled environment with low levels of airborne dust and dirt. Cleaning and inspecting surfaces on the bearing before installation is important to achieve the highest performance.
Other Considerations
Bearings require careful handling during storage. Dropping a bearing can cause serious damage and put workers at risk of injury. Before installation, a bearing needs to be handled carefully and should be lubricated properly. Lubrication helps to protect the bearings from corrosion, contamination and damage due to excessive loads. When selecting a lubricant, it is important to choose one that is compatible with the bearing material.
Be sure to inspect the bearing for wear or damage before installation. It’s essential to ensure that all components of the bearing, including the housing, seal and any additional parts, are in good condition before use. Keep the bearings in their original packages until the time of installation. Pay special attention to any specific instructions from the manufacturer to ensure that the bearing is stored correctly and installed properly.
Taking proper precautions when it comes to storing bearings will ensure that the bearing will perform correctly and safely. Monitoring the temperature, moisture, and cleanliness levels of the stored bearing is essential for long-term performance and will help to prevent any damage or injury.
