Development of Grease Lubricated Ball Bearings

COURSE NO: M02-048
Development of Grease Lubricated Ball Bearings
Course Highlights

This online engineering PDH course details the pitfalls and successes that led to developing the bearing package that met the final goal and makes recommendations on how to improve the design even further. It takes the reader through a three-year program that successfully developed a high speed grease lubricated ball bearing for aircraft accessory application. The first of this two-part program developed a high speed bearing package from six different separator grease combinations from which a combination that exceeded the program goal of operating at 50,000 rpm (one million DN) for 50 hours was selected.


Grease lubricated ball bearings are a design tool that no engineer should overlook. They are a self-contained, self-lubricated highly efficient engineering package that can provide a lifetime of service in a small space with little or no maintenance.


This 2 PDH online course is intended for mechanical engineers, aeronautical engineers, machine design engineers, and anyone else who is interested a gaining an understanding of grease lubricated ball bearings.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Understanding ball bearing design, terminology, variations and use
  • Knowing how a grease lubricated ball bearing can benefit the aircraft accessory industry
