A simple one-piece sleeve is sometimes better for reducing friction than complex rolling-element bearings. Besides being greaseless, journal bearings can be made out of high-tech plastics for weight ...

Tribology, the science of friction, lubrication and wear, is fundamental for designing robust interfaces in mechanical systems. In the context of journal bearings—critical components supporting ...

With the higher rotational speeds and loads in bearings, the gaseous cavitation becomes more and cannot be ignorable in the bearing designs. However, there is no enough research in non-equilibrium ...

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 ...

ABSTRACT A simple method is frequently used to calculate a reciprocating engine’s bearing load from the measured cylinder pressure. However, it has become apparent that engine downsizing and weight ...
