The main advantage of sintered technology is that, we can vary the density of parts based on our application. And sintered bearing bush is the best example of the use of sintered technology. These bearing can be made of low to moderate density (6.0-6.6 gm/cc). Which allows it to be impregnated with the oil. So Porosity of the bearing is filled up by the lubricating oil. The working principle of sintered bearing is that, during run time of shaft a thin film of oil is generated in between & it lubricates, avoids friction. And in Ideal time oil again goes into the bearing. So in total life cycle of the bearing we don’t have to lubricate it with external oil. These has wide application in automotive & non-automotive sector like home appliances.
