Due to normal friction and wear, even in properly lubricated moving machine elements, it is not uncommon to find small amounts of debris in used lubricants. The wear debris analysis technique has been applied for monitoring machine condition for quite sometimes. However, most of the works reported to date have been focussed for oil - lubricated machinery. Actually, very little primary material of the application of used grease analysis technique for plain bearings is to be found in the periodical literature. The identification of the cause of damage or failure in plain bearings is crucial before remedial action can be taken to prevent further damage. The first step is a visual examination of the wear debris and/or contaminants in the used grease samples. In addition, this step can then be followed up by visualization of the damaged parts, if applicable. Once failure has been initiated, the origin mechanism may lead to other failure mechanisms and it is essential to identify the original cause. In this particular work, "systematic used grease wear debris analysis" is proposed. Preliminary results are presented and discussed.
