Workshop Stream 5

Bearing Failure Root Cause Analysis is a MUST!

Lecturer: Per Arnold Elgquist Olsson


Do you want to avoid bearing failures to repeat? The only way is to realize root cause failure analysis to identify the causes for the failures and determine and implement the required corrective actions!

In this Workshop you will learn the basics:

1. How long should bearings really last? This is most important to know in order to define if the bearing has reached its calculated life or if it is a premature failure. I will present an example to show the importance.

If it is a premature failure the failure analysis is a must in order to make the replacement bearing last as long as required. If not, the replacement bearing will fail premature due to the same cause!

2. Learn how to perform a bearing root cause failure analysis in a most practical and effective way.

3. Get to know the different failure modes for bearing failures and their causes.

4. Learn the 10 most relevant causes for bearing failures.

5. Learn how to select use the most suitable predictive technologies in order to detect initial failures, or even symptoms of failures before the initial irreversible failure occurs, in order to avoid catastrophic failures. These are most often unplanned and most costly due to collateral damages and long downtime, and, in many cases make the failure analysis most difficult due to the advanced damages.

During the workshop several practical exercises will take place where you will learn how to apply the process of bearing failure analysis in an easy and practical way.


1. The importance of calculated bearing service life.

2.  A bearing root cause failure analysis in a most practical and effective way.

3. Which are the different bearing failure modes and how they point out the required corrective actions.

4. Which are the 10 most relevant failure causes for rolling element bearings.
