Nowadays, CBM system became more common method to reduce cost spent on destructive inspections. With CBM, we can reduce significant maintenance cost since we can judge the machine need to be destructed or not. We can also do premeditated inspections. CBM is very useful for tribological appar atus. Especially, oil analysis has much higher sensitivity and speed than other diagnostic method such as vibration, temperature and etc. At TRIBOTEX Co., Ltd., we diagnose several conditions of machine by using variou...

Accelerated Deterioration Test of Roller Bearings

Abstract: At the maintenance scene, experience shows that a change of wear debris amount in oil occurs in connection with a change of machinery’s lubricating condition. This study reports a result of destruction test using an actual sliding bearing of lifting pump which is made up an extreme lubricating condition. The bearing is monitored a wear debris occasion in real-time for confirming a correlation between the change of lubricating condition and the change of wear debris amount in oil. As a result,...
