In a world where maintenance professionals are retiring and tribal knowledge is walking out the door, this handbook serves as the permanent, standardized archive of best practices. It tells you exactly when to change the oil, how to read the report, where to place the breather, and why the grease is leaking.

In the high-stakes world of industrial machinery, lubrication is not merely a maintenance task—it is a strategic discipline. Poor lubrication practices account for approximately 54% to 80% of all bearing failures. In hydraulic systems, that number can climb even higher. Yet, for decades, lubrication was treated as a secondary skill, often delegated to the least experienced team members with nothing more than a grease gun and a guess.

If you own the third edition, recycling it for the is a worthwhile investment—specifically for the IoT, ultrasonic, and ISO 4406 updates. If you have never owned a copy, you are currently practicing lubrication by folklore. It is time to practice by science.

Essential reading. 5/5 stars. Keep a copy on your desk and a waterproof copy in your tool cart. Call to Action: Check with major technical publishers such as Noria or Reliabilityweb for the latest printing of the 4th Edition. Ensure you receive the digital companion files if available, which include printable checklists and contamination control posters. Your machinery—and your bottom line—will thank you.
