...flatlines. A typical sintered journal bearing develops cracks when subjected to repeated impact loading. Many engineers consider external lubrication systems for journal bearings a necessary evil. The approach adds design complexity and another item to be routinely serviced. Not to mention, liquid...

...very slowly. Wear occurs during start-up and slowdown when speed is too low to produce sufficient fluid pressure to support the bearing surfaces on a lubricant film. If hard debris imbeds in a babbitt or plastic bearing and protrudes above the bearing surface, the journal can wear seriously during...

Numerous oil and grease-lubricated bearing designs rely on adequate lubricant film thickness for smooth and trouble-free operation. Engineers must check that films are sufficiently thick so asperities peaks of surface roughness between mating surfaces don't touch. Dow Chemical Endowed Chair...

High-operating temperature can spell trouble for journal bearings. Here are some ways to avoid it. Director, Center for Rotating Machinery Plastic flow at 305 F in a 16-in.-diameter babbitt journal bearing. Journal bearings that overheat signal-a problem with lubrication, misalignment...

...properly reaching bearings can trigger TIS, including a clogged oil filter. Bearings starved of lubricant generate excessive frictional heat. For example, a hydrodynamic journal bearing with a full film of lubricant separating surfaces typically has a friction coefficient, of about 0.001 to 0.008...

Journal bearing design is complex. It involves optimizing clearances, bearing length, minimum film lubricant, viscosity, flow rate, and inlet slots. Design equations are available, but their solution is time consuming unless done on a computer. Fortunately, these equations have been reduced...

...to reduce friction and wear. Fluid lubricants would have to be used in sealed systems that would add weight to the brace. Coating the inside of a journal bearing prevents metal-to-metal contact with the mating shaft. Low-friction coatings are used on bearings for two reasons. The first is as a backup...

...the self-lubricating process. Wood bearings lubricate in three modes: boundary, full film (hydrodynamic), and mixed film. Under fullfilm lubrication, a thick film of lubricant separates a journal and bearing so service life is nearly infinite. Boundary lubrication involves bearing-journal contact so wear...
