5 Reasons For Bearing Failure

5 Reasons Why Bearings Fail.

Yes, things break. Just the other day, we dropped into a local coffee shop and they had a maintenance guy onsite repairing one of their dispensing machines, in the middle of a busy lunch schedule. What a time for something to break down… but it happens. It got me thinking about the nature of things, computers and network systems for example, something I am all too familiar with as an experienced computer network techie that I am. It gave me inspiration to put this quick list together for you regarding the failure of bearings.  I set about thinking of ten reasons why ball bearings fail.

  1. Lubrication Failure:

Probably the most common cause of bearing failure. Insufficient lubrication, use of incorrect lubricant or excessive temperatures. We mentioned excessive on our previous update in relation to hydraulic seal failure. Excessive running temperatures degrade the lubricant. You should see discolouring of the roller element in the bearing, this is a sign of excessive wear. This is counteracted or prevented by ensuring the correct lubricant or grease is used and make sure there is no grease loss. This should eliminate premature bearing failure.

  1. Contamination:

Caused by foreign particles getting into the system – such as dirt and dust or workplace waste. This causes denting of the rolling elements, which results in vibration. Lubricants should be filtered and work areas and tools kept clean.

  1. Improper mounting.

This is an obvious one. You notice that bearings are mounted on a rotating ring, and are done on a press-fit. If the bearing wasn’t manufactured properly, the bearings will vibrate with the result being denting, wear, cracked rings, high operating temperatures, early fatigue and eventually premature bearing failure. Proper mounting instructions should be followed when the bearing in placed in situ as a prevention to bearing failure.

  1. Bearing Misalignment

Bent shafts can cause misalignment, and the result is similar to improper mounting above. Other causes could be improper installation or the press-fit mechanism was off calibration. You should notice a wear path that is not central or uniform. Inspect the shafts and housings and use good locknuts.

  1. Bearing Corrosion

In our climate in Ireland, the moisture and condensation in the air can cause corrosion, as well as low quality lubricants and greases, lack of replacing certain parts leading to rubbing of the bearing. Red or brown stains on the raceway or bearings will indicate this. This abrasion will cause wear to the required smooth surface of the ball bearing.  If you can get sealed bearings, this will help avail the problem of bearing corrosion, and try to get bearings made from stainless steel.

Feel free to comment with feedback or suggestions of worn bearings… even better, send your images of broken or worn bearings… we’d love to feature in one of our future updates.

All the best,



4 Reasons for Hydraulic Seal Failure

Four Common Errors with Hydraulic Equipment

1. Not changing the hydraulic oil

Oil should be changed at the end of its usable life. Oil breaks down over time, resulting the degradation of the oils base and the depletion of any additives in the oil. There are many variables that determine when this time comes, from frequency of use, operation temperature and the environment that the oil is running. With the prices of oil continually rising, replacing too soon is costly and leaving running in the engine too long can have a damaging effect on the engines parts. Simply replacing after a specific period of time is not enough. The only true measure of oil usability would be to do a proper analysis.

2. 6 Believing Hydraulic Components are Self-Lubricating

Dont assume that all hydraulic components are self-lubricating. You cannot afford the luxury to assume a part will self lubricate if it fails to do so. What happens if the part fails and the result is a complete system break down. Nasty! Hydraulic components can be seriously damaged. In some cases, they may work OK for a while, but the harm incurred at start-up then dooms them to premature failure. Just ensure you have replaced the fluids/oil.

3. Letting the Machinery Run Too Hot

Just like an engine, the fastest way to burn or wear hydraulic seals or components is to run the engine or equipment too hot. The same rings true for all types of hydraulic components, and is not limited to hydraulic seals, but other materials such as hydraulic hose and the hydraulic oil itself. So how do you know that the system is running too hot? This really depends on the viscosity of the hydraulic oil and the type of components in the system. As oil temperature increases, viscosity decreases, and falls below the adequate required lubrication for the hydraulic seals. Temperatures above 82 degrees (Celsius) will damage most hydraulic hose and hydraulic seal components, and advance the degradation of the hydraulic oil base. For these reasons, it is vital to monitor core temperatures.

4. Using the Wrong Hydraulic Oil

We would consider that oil is the most important component of any hydraulic system. Hydraulic oil is not only a lubricant but is also the means to transfer power though the system. This dual role makes viscosity the most important factor as it affects the machine performance and life.
Oil viscosity will determine the maximum and minimum starting oil temperatures. Is the machine starting up in an extreme cold environment or operating in an extremely hot environment. If you use unsuitable oil in either of these environments, hydraulic failure of components or engines can occur.
Also, within these tolerances of temperature, we also have to deal with the power loses when oil viscosity is reduced, which will lead to power loss or even failure from friction and internal oil / hydraulic fluid leakage. Using the wrong viscosity oil will result in increased power consumption (diesel or electrical).
Always consult the manufacturer of your equipment to use the correct oil as specified on the equipment manual.
