Abstract: A threaded installation is provided. The threaded installation includes a nut, a bolt, and a housing. The housing includes a threaded hole. A first threaded connection is formed where the bolt is threadably coupled with the nut, and a second threaded connection is formed where the bolt is threadably coupled with the threaded hole. The first threaded connection is characterized by a first flank angle, Θ2A, of threads of the bolt or threads of the nut. The second threaded connection is characterized by a second flank angle, Θ3B, of threads of the bolt or threads of the housing. The flank angles, Θ2A and Θ3B, satisfy the following equation:

Abstract: 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.

Abstract: The present disclosure provides for a force breaker assembly. The assembly includes a housing having a first channel, a body within the housing and including an engagement surface. A second channel is formed in the body. A spring is positioned adjacent the body. A snap ring is positioned within the housing and about the body. When a load is applied to the engagement surface that is below a preset limit, the ring remains engaged within the first and second channel, retaining the body in an extended position. When a load is applied to the engagement surface that is at or above the preset limit, the ring is expanded out of the second channel and into the first channel or is compressed out of the first channel and into the second channel, such that the body is forced into a depressed position.
