2140 Rolling Element Bearings


Description
Rolling Element Bearings briefly describes how bearings work and the limitations of various styles offered in average machines. Major emphasis is placed on selection, upgrade strategies, and work processes that reduce premature bearing failures. The course includes guidelines that best-in-class users can implement to estimate costs and justify upgrades.

Learning Outcomes:


• Understand bearing construction, including differences in axial vs radial bearings and bearing preload
• Identify causes of black oil and proper use of oil ring lubrication
• Determine appropriate lubrication method for your application and important guidelines for each type
• Understand root causes of high bearing temperature and bearing failure

Chapter Summaries:


CHAPTER 1: BEARING TYPES AND FAILURES


This chapter provides an in-depth analysis of different rolling element bearings used in pumps, detailing premature bearing failure causes. It explores performance trade-offs, bearing nomenclature, cage configurations, and materials, updating the bearing life ranking and offering insights into performance and longevity.

CHAPTER 2: BEARING SEALS


This chapter delves into bearing failure causes, focusing on FRETT and modern protector seals. It highlights features and benefits of magnetic and modern bearing housing seals, emphasizing their desirable characteristics in enhancing performance and preventing failure.

CHAPTER 3: BEARING LUBRICATION


This chapter explores various bearing lubricants, focusing on constant level lubricators in pumps. It identifies problem areas, provides upgrade features, discusses oil ring issues, and includes a Q&A section. The chapter explains the superiority of flinger discs over oil rings and the advantages of oil mist lubrication.

CHAPTER 4: GREASE LUBRICATION


This chapter explores grease as a bearing lubricant, particularly in lifetime sealed bearings as a new technology. It outlines grease advantages over oil in self-lubricating bearings, discussing how grease contributes to enhanced performance, reduced maintenance, and improved reliability.
