Troubleshooting And Bearing Failure Analysis

Posted December 7, 2015 by admin

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.

2. Misalignment
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.

3. Corrosion
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.

Bearing Maintenance – What You Need To Know

Posted November 16, 2015 by admin

Keeping your roller or ball bearings in tip top shape is essential to a great spin, whether it’s on your vehicle, skateboard, or household appliance. The good news? With just a little bit of bearing maintenance, you’ll be at the top of your game.

1. Keep your bearings free of moisture and dirt, and be sure to keep them well lubricated. This requires attention on your part. You’ll never know if your bearings are looking rough unless you actually take the time to inspect them.

2. Keep an ear out. Just as you should be making a visual check on your bearings, you’ll also want to listen for any unusual sounds. When bearings become dirty they may start emitting a squeak. This means they are in desperate need of a cleaning. Use your preferred cleaning solution and dry your bearings ASAP. Once dried, reapply lubricant to prevent any wear or rusting.

3. Never lubricate dirty bearings. While it may seem like a quick fix for the time being, you should never attempt to oil or lubricate bearings if they are unclean. This may only further harm the bearings by driving the dirt into the gears.

4. Talk to people who know what they’re doing. When it comes to “DIY Bearing Maintenance” make sure you have a friend or associate who knows exactly what they’re talking about. This may only end up ruining your bearings. Instead, choose a knowledgeable bunch (Like us!) who knows exactly what they’re talking about.
