Patent number: 5789354Abstract: A lubricative composition which can retain lubricating oil or grease without degrading it, which is heat-resistant and mechanically strong, and can be used continuously for a much longer time than conventional ones without the possibility of shortage of lubricant supply. It includes a first component, which is a modified silicone oil having reactive organic groups, a second component, which is a curing agent having organic groups that react with the reactive organic groups, and a third component, which is a lubricating oil or grease. The third component is retained in a three-dimensionally reticulated structure of silicone formed by polymerizing the first and second components in the third component. The third component has no compatibility with either the first or second components.Type: GrantFiled: December 5, 1996Date of Patent: August 4, 1998Assignee: NTN CorporationInventors: Hidenobu Mikami, Mitsunari Asao
