Do you know what to look for when something’s wrong with your bearings? We’re looking at the VNC process for troubleshooting & bearing failure analysis.
When a roller or ball bearing gets cracked or damaged, it may set your machine to a grinding halt. A bearing failure can be frustrating to say the least. At VNC we know when your vehicle or mechanical application fails due to faulty ball bearings; these setbacks can mean wasted time and money lost. Due to bearing failure, it’s important to know what causes the defect and how you can prevent future issues with your bearings. We’re looking at 4 ways to troubleshoot bearing failures.
Reasons For Bearing Failure – Analysis
When it comes to bearing failure troubleshooting, if you don’t know the problem, you can’t know the solution. Here are some common reasons for ball bearing failure and how to troubleshoot the issues.
1. Not Enough Lubrication
It is said that up to 80% of bearing failure is caused by a lack of lubrication. Improper lubrication can break down the bearing and cause it to function improperly. If your bearing is damaged by improper lubrication it will show discoloration and wear. Always use the correct amount and type of lubricant for your bearing to keep it in good working order.
When a roller bearing becomes misaligned, it will put a stop to the fluidity of motion. In most cases, misalignment will eventually lead to improper installation, separating, and overheating. Do a routine check and inspect housings and shafts to ensure they are in working condition.
Due to acid, moisture, or broken grease traps, condensation can ruin a ball bearing. You can easily identify ball bearing corrosion spots by doing a visual check of the bearing. If corroded, the bearing will show signs of brown or red staining on the rolling portions. The bearing will also display preload loss and increased vibration when running.
4. Bearing Fatigue
Often called “spalling” in the bearing world, fatigue happens as a result of excessive overloading and misuse of the bearing type. To combat bearing fatigue, check for an increase in noise and vibration when your system is running, and be sure to replace the bearing according to the need of your application.
