摘要： A radial bearing assembly is provided. The radial bearing assembly includes polycrystalline diamond elements, each having an engagement surface in sliding engagement with an opposing engagement surface. The opposing engagement surface includes a diamond reactive material. The radial bearing assembly may be deployed in a variety of components and applications, including in rotor and stator assemblies. Also provided are methods of use of the radial bearing assembly, as well as methods of designing the radial bearing assembly.

摘要： A downhole tool for use in a downhole drill string is provided. The downhole tool includes a rotor movably coupled within a stator, and a drive shaft movably coupled within a bearing housing. The drive shaft has a first end coupled with the rotor and a second end coupled with a drill bit. Bearing assemblies interfaces engagement between the drive shaft and the bearing housing, including polycrystalline diamond elements, each with an engagement surface, and an opposing engagement surface of a non-superhard metal.
