Analyzing Bearing Failure

In Mechanical

Details

Learn the purpose of bearings and demonstrate how bearings reduce friction and maintain the alignment of operating equipment.

Prerequisites

Completion of the lesson Introduction to Bearings is recommended.

Description

This is the second lesson in the iKNOW™ Bearings Library. This Lesson explains the purpose of bearings and demonstrates how bearings reduce friction and maintain the alignment of  operating equipment. The basic operation of anti-friction bearings and plain journal bearings is demonstrated as well as the importance of full fluid film lubrication and proper lubrication clearance. Additionally, indications of various premature bearing failures are discussed.

Objectives

Dismount anti-friction bearings using a bearing press and/or a bearing puller, Inspect the bearing for signs of failure, Clean the shaft and check for taper and out-of-round using the proper measuring instruments, Clean the housing and check for damage, Select the proper bearing for replacement, if necessary, Properly orient a bearing prior to installation,Mount a bearing using an induction heater and/or an arbor press, Measure the bearing’s inner and outer clearances during installation and Properly lubricate bearings per manufacturers’ recommendations.
