Misalignment. Faulty mounting practice 4. In many cases, misassembly will result in premature failure of the bearing. The root cause of failure was excessive endplay in the TRB bearings E1/E2, which was caused by wear on the bearing locknut due to spinning of the IR of bearing E1. 1. 1. 472 0 obj

Vibratory loads, or system dynamic loads depend on the interrelation of the components in the entire system with one another and torquemeter readings or a study of the system is required to assess instantaneous loads. Suggested Procedure for Bearing Analysis Follow the steps below for an accurate and complete analysis when investigating any bearing damage or system breakdowns. INTRODUCTION Keywords: Bearing failure, Rolling element, Ball bearings, Roller Bearing, Failure analysis. This has a negative impact on your reputation, and your bottom line. the bearing unserviceable. Three major classifications of premature spalling are lubrication, mechanical damage, and material defects. However, the information is not sufficient to do in-depth bearing failure analysis and does not compensate for experience neces - sary in this domain. Gather operating data from bearing monitoring devices; analyze service bearing failure is due to a combination of sev eral of these causes. %%EOF
To help mitigate failures and provide remedial action, AST can expertly examine, test, and analyze a wide range of bearing … 4. Generally, the service life of bearings is expressed either as a period of time or as the total number of rotations before the occurrence of failures in the inner ring, outer ring or rolling element because of rolling fatigue, due to repeated stress. CAUTION: After dismounting, never disassemble, clean or wash the bearing and protect it against dust or damp before sending it for investigation and remanufacturing. Bearing Failure Analysis. Root Cause Analysis 16 3. Misassembly 5 When bearings fail to meet their expected life or performance levels, the consequences are far-reaching and include, increased downtime, high maintenance costs, loss of revenue, and missed deliveries. Bearing failures and their causes Bearings are among the most import-ant components in the vast majority of machines and exacting demands are made upon their carrying capacity and reliability.
