Bearing Failure Warning Signs

width=113Downtime caused by bearing failure can either be moderately inconvenient or an absolutely disaster, but either way it is better to stay on top of the situation. Failing to replace a bearing that has worn out or become damaged can lead to further damage to other parts of the application, causing even more downtime.

Here we will look at the common causes of bearing failure, and the three main warning signs to look out for that indicate your bearing needs to be replaced by an industrial bearings supplier like Yorkshire’s YB Components.

Common Causes of Bearing Failure

Using the wrong kind of lubrication is one of the most common causes of bearing failure. It is also detrimental to use the wrong quantity of lubricant, even if it is the correct type. Too much lubrication can lead to leakage which can have a variety of knock-on effects, while too little lubrication will cause the bearing to run dry and minimise its lifespan.

Another common cause of bearing failure is contamination, which can happen in several different ways. Firstly, high-pressured wash-downs can emulsify the lubricant, rendering it inefficient or even entirely ineffective. Wear and tear on seals can also contaminate the bearings, with worn-off particles entering and spoiling the lubricant. Also be careful when applying lubrication, as this is a very common cause of contamination. Always ensure all grease guns and oil applicant tools are completely clean before applying lubrication to bearings.

Bearing Failure Warning Sign #1: Vibrations

Excessive vibration will be caused by the rolling elements bouncing around on the raceway surface during the application’s operation. This happens when the bearing is failing or has completely failed, and the raceway surface of the bearing has been damaged by abrasion.

Always replace the bearing as soon as you notice it suddenly start vibrating beyond normal during operation.

Bearing Failure Warning Sign #2: Noise

Bearing failure is also imminent if your application starts making excessive noise. The new noise is being made by the raceways of the bearing being damaged, which causes the rolling elements to rattle around during operation. This will often occur at the same time as excessive vibrations.

To replace a bearing, contact an industrial bearings supplier. Yorkshire’s YB Components can supply such parts all over the UK and the rest of the world.

Bearing Failure Warning Sign #3: Heat

Excessive heat is often caused by friction, usually when the rolling elements of a bearing are running on damaged raceways or on raceways that have not been adequately lubricated. The friction generates energy which in turn increases the temperature of the bearing during operation. The higher the level of damage, the higher the temperature is likely to become, so it is important to replace the bearing and any damaged raceways as soon as possible once it start producing excessive heat.
