Abstract
A Laboratory bearing test rig was constructed to study wear of three high speed roller bearings simultaneously under different conditions of loading and lubrication. During the last year the rig was further developed to improve running capability under increased loading, and for safe operation test conditions were monitored by a computer. A test run of 355 hours duration was performed during which wear of the bearings were monitored using DR ferrography. Four test bearings from the rig were examined using metallography and microhardness measurements. Wear debris particles were collected from oil samples of the bearings using ferrography. These were studied using bichromatic microscopy, scanning electron microscopy and energy dispersive x-ray microanalysis. To understand wear mechanisms in the bearings, the results of ferrography were correlated with the metallographic results.
