Why is my bearing suddenly making excessive noise

What causes a bearing to be noisy?

If your bearing has suddenly started making noise during operation, there is a problem with your bearing. The excess noise that you’re hearing is created when the raceways of the bearing have become damaged, causing the rolling 

elements to bounce or rattle during rotation.

There are many different causes of a noisy bearing but the most common is contamination. It could be that contamination occurred during the installation of the bearing, with particles remaining on the raceway which caused damage when the bearing was first operated.

Shields and seals can become damaged during lubrication of the bearing, rendering them ineffective in protecting against the ingress of contamination – a particular problem in highly contaminated environments.

Contamination is also common during the lubrication process. Foreign particles may become stuck to the end of the grease gun and enter the machinery during relubrication. WSBC 24044 CC/W33 bearings online, pls click here :

These foreign particles make it into the raceways of the bearing. When the bearing begins operation, the particle will start to damage the raceway of the bearing, causing the rolling elements to bounce or rattle and creating the noise that you are hearing.

What should you do if your bearing starts making noise?

The noise coming from your bearing may sound like whistling, rattling, or growling. Unfortunately, by the time you hear this noise, your bearing has failed and the only solution is to replace the bearing as soon as possible.

You may find that adding grease to your bearing quietens the noise. That means it’s fixed the issue, right?

Unfortunately, this isn’t the case. Adding grease once your bearing has started to make noise will only mask the issue. It’s like putting a plaster on a stab wound – it needs urgent attention and the noise will only come back. You can use condition monitoring technologies such as vibration analysis or thermography to predict when the bearing is likely to fail catastrophically and to calculate the latest point at which you can safely replace the bearing.

How to prevent bearing failure 

It can be tempting to just replace the failed bearing and carry on with your everyday business operations. However, it’s important to not just replace the bearing but to also look for the root cause of the failure. Performing root cause analysis will identify the underlying issue, allowing you to put mitigating measures in place to prevent the same issue from reoccurring. WSBC 24032 CC/W33 bearings online, pls click here :

Making sure you’re using the most effective sealing solution for your operating conditions and checking the condition of your seals every time you perform maintenance can help to guard against the ingress of contamination.

It’s also important to make sure you’re using the right fitting tools for your bearings. This will help to prevent damage from occurring during the mounting process.
