Author(s) : JOHNSON M. S. Jr

Type of article: Article

Summary

This article discusses an example of an outer race-bearing defect on a 1250 ton (4400 kW) air-conditioning chiller. The defect was detected using off-the-shelf portable vibration analysis hardware and software. This article discusses methods used to diagnose and trend the bearing defect using vibration spectra as an indicator of the bearing condition. The diagnostic methods covered are universally applicable to other types of machines (pumps, fans, gears) with rolling contact bearings.
