dss+ Bearing Failure Mechanisms: Principles of Lubrication

Published on Dec 27, 2022

eLearning (15 min)


All M&R workers who service machinery with bearings


Automotive, Food and Beverage, Chemical and Petrochemical, Electronics, Oil and Gas, Metals and Mining, Transportation, Manufacturing, Power and Utilities

Topics Covered

Includes calculating the ideal lifespan of a bearing and actions that can lead to a bearing reaching its maximum lifespan, specifically:

  • Understanding bearing life and where to find the lifespan of specific bearings
  • Lubrication dynamics and how an oil wedge is formed within an active bearing
  • Principles of hydrodynamic lubrication in journal bearings
  • The concept of conformity
  • Principles of elastohydrodynamic lubrication in rolling element bearings

Key Models & Tools

High definition visual models, videos and interactive exercises are included to engage workers in understanding the relationship between bearings and lubrication, and best practices to maximize bearing life.

Course Code


Key Outcomes
After this course, learners will be able to identify the lifespan of bearings in their workplace and implement practices that maximize bearing life. They will understand the relationship between bearings and lubrication, and how to differentiate between hydrodynamic and elastohydrodynamic lubrication.
