Maximizing Bearing Life
Bearings are essential components in many machines, from electric motors and aircraft engines, to fans and pumps. When working correctly, bearings deliver smooth, low friction operation and long bearing life. Poorly maintained bearings, however, can wear quickly, resulting in expensive downtime, repairs and greater maintenance costs. Bearing life is maximized when the lubrication and application requirements of the bearing are carefully observed.
Identify the Proper Bearing and Lubrication
The best way to increase bearing life is to choose the right bearing and lubricant for the application. Factors such as speed, operating temperature, load, and the operating environment should be considered with the input of the bearing manufacturer before selecting a bearing. Using the wrong bearing and/or lubricant can significantly reduce bearing life.
Maintenance Procedures
Regular maintenance is critical to increasing bearing life. Regular inspections of all bearings should be regularly scheduled. During inspections, visual signs of debris, dust, dirt, or wheel vibration can point to a problem, in addition to audible signs such as squealing or bearing noise. If these signs are observed, immediate action should be taken. Additionally, bearing housings should be inspected for possible wear, exceeding expected operating temperature, contamination or external pressure.
If lubrication is recommended for the bearing, it is important to use the recommended lubricant, and in the proper amount. Too much or too little lubricant can result in wear and reduce bearing life.
If the bearing is sealed, it is best to leave it sealed. If a bearing seal is damaged, or if a bearing is exposed to debris or dust, it may need to be cleaned and relubricated. This process should be done cautiously, as too much lubrication or foreign contaminants can reduce bearing life.
The appropriate bearing fits must also be chosen to ensure that the bearing performs correctly and works in the application as designed. Proper fits are necessary to prevent bearing failures, reduce noise and vibration and increase bearing life.
Proper Handling and Storage
When handling and storing bearings, the right procedures should be followed to prevent damage. When transporting bearings in bulk, anti-static material should be used to prevent electrical damage. When unpacking bearings, the manufacturers instructions should also be followed to ensure correct installation and fitting.
Additionally, bearings should be stored in a cool, dry area. In damp or humid conditions, rust can form on the bearing, reducing bearing life.
Summary
To maximize bearing life and performance, it is essential to consider the application, choose a proper bearing and lubricant, regularly maintain and inspect the bearing, and properly store and handle the bearing. By choosing the best bearing for the job, properly lubricating and maintaining it, you can ensure that your bearing operates properly and lasts as long as possible.
