Large slow speed diesel engines are usually of the crosshead type and have various arrangements to deliver lubricating oil directly to the crosshead bearings and guides to ensure adequate lubrication. Why are the crosshead bearings considered differently to the other bearing in this type of engine in respect of lubrication requirements?
The lubricating oil has further to travel to the crosshead bearing and so a separate arrangement is necessary
The crosshead bearing is more heavily loaded than other bearings in the engine so requires more oil to keep it cool.
The crosshead bearing is closer to the engine cylinder and therefore runs hotter.
The running surfaces oscillate relative to each other during operation rather than rotate and therefore full film hydrodynamic lubrication is not possible.
