Abstract: A fitting has a first housing including a first body and a second body. The first body defines a first channel and a second channel, and second body defines a third channel that is co-planar with the first channel and a fourth channel that is co-planar with the first channel. First bearings are disposed within the first channel and the third channel, where the first bearings rotatably coupled the first housing to the second housing. Additionally, second bearings are disposed within the second channel and the fourth channel, the second bearings rotatably coupling the first housing to the second housing. A plug couples to the first housing, a gasket is disposed between the plug and the first housing, and a passage is defined at least in part by the first housing, the second housing, and the plug.

Abstract: A machine, such as a hauler at a mining site, includes one or more bolted (clamped) joints. Friction coatings are applied to surfaces of two or more materials being clamped to reduce clamp load loss. The friction coatings include one or more coated surfaces and one or more interstitial spaces between the coated surfaces. Various materials may be used as the friction coating including, but not limited to, a tungsten/carbide or stellite/carbide alloy, iron base alloys such as POLYMET alloys, including PMET 290 (an alloy of iron, chromium, boron, manganese, silicone, and nickel), a nickel chromium alloy, e.g., Ni-20Cr, aluminum oxide (Al2O3) particles, and various combinations of these and other suitable materials.
