BEARING ROOT CAUSE
Failure Analysis
MUE251 | REVISION 001 PAGE 2 OF 5
Course Introduction:
This course is designed is to provide pertinent information and practical insight to the
participants for improving the performance of rolling element bearings, which then enhances the
reliability of rotating equipment. The course is designed for participants to understand the
functions of bearings in relation to rotating equipment, its installation, its performance and to
know the major signals/symptoms of Bearing failure. A basic understanding of the principles and
practices of predictive maintenance is also covered. Participants can use the skills and knowledge
gained in this course to: Minimize bearing failures in equipment thus reducing downtime and
cost; Perform regular preventive maintenance on equipment’s; and Quickly respond to bearing-
related equipment and system failures. The course discusses the modes of failure of bearings in
equipment’s root cause analysis, how to check root cause and what methods available to
eliminate them for the future.
Course Objectives:
At the completion of the course, participants will understand:
Types of Bearings.
The functions of a bearing in rotating machines.
The factors effecting the performance of rolling element bearings
Bearing mounting and dismantling procedures.
Shaft alignment and how to correct for misalignment. Bearing Inspection methods
Causes of bearing failure.
Identify the symptoms of bearing trouble and describe how to remedy each situation.
Shaft alignment, compensation for misalignment.
Root cause and Failure analysis.
Installation care and precaution.
Selection of lubricants.
Replacement procedures.
Tools for servicing.
Who Should Attend?
The course is ideally suited for Maintenance Engineers, Service Engineers, Operations staff, and
Machine repair persons from any industry using rotating equipments. It is recommended for
Managers and Engineers responsible for bearing performance and reliability. Rotating equipment
engineers, reliability engineers, millwrights, mechanics, maintenance supervisors and anyone
interested in rolling element bearing and rotating equipment performance will find it useful.
