Bearing Brinelling: The Silent Killer
Bearing Brinelling: The Silent Killer
Bearing brinelling is a common problem that can lead to premature bearing failure. It occurs when a static load is applied to a bearing, causing the balls or rollers to indent the raceway. This can create a permanent deformation that can reduce the bearing's load capacity and service life.
Causes of Bearing Brinelling
Bearing brinelling is typically caused by one of two things:
- Excessive static load: When a static load is applied to a bearing, the balls or rollers can indent the raceway if the load is too heavy.
- Insufficient lubrication: If a bearing is not properly lubricated, the balls or rollers can rub against the raceway, causing wear and brinelling.
Effects of Bearing Brinelling
Bearing brinelling can have a number of negative effects, including:
- Reduced load capacity
- Shorter service life
- Increased noise and vibration
- Bearing failure
Preventing Bearing Brinelling
There are a number of things that can be done to prevent bearing brinelling, including:
- Using the correct bearing for the application: The bearing should be sized appropriately for the load that it will be subjected to.
- Properly lubricating the bearing: The bearing should be lubricated according to the manufacturer's instructions.
- Avoiding excessive static loads: If possible, avoid applying static loads to bearings. If a static load must be applied, use a bearing that is designed to handle it.
Troubleshooting Bearing Brinelling
If you suspect that a bearing is experiencing bearing brinelling, there are a few things you can do to troubleshoot the problem:
- Inspect the bearing: Look for any signs of brinelling, such as indentations or wear on the raceway.
- Check the lubrication: Make sure that the bearing is properly lubricated.
- Measure the static load: Determine if the static load is too heavy for the bearing.
Conclusion
