Powder metallurgy is a metal-forming process of ferrous-powdered materials performed by pressing and sintering metal powder compacts near to net shape of the final component. It allows very complex geometries and intricate features. The process has existed for more than 100 years. It is now widely acknowledged as a superior way of producing high-quality sintered, structural components for a large array of applications in different industries.
Oil Sintered Bearing is made of bronze or iron or stainless steel powder with lubricating oil vacuum sintered. It is mold pressed by high pressure then sintered in high temperature, after that, put it in high temperature vacuum and soaked in oil. This bearing is used in electrical appliances, power tools, textiles machinery and automobile industry. Like electrical fan, electrical motor, juicer, mixture, etc.
