Same type of bearings are used in these engines so should not be a problem.

Actually, the bearings in the car engines should last longer BECAUSE there is only a lateral load and a minor side load.

Airplane engines DO produce a thrust (side) load to the bearing and less of a lateral load. It would be great to see a mfg design an engine with both types of bearings installed to take on both types of loads.

The reason bearings in car engines do not last long is because of the rpms they are subjected to and possible lack of lubrication to the bearing itself. That and all the dirt that gets picked up and worked into the bearing balls themselves. 'Sealed' Bearings ??......[sm=lol.gif]
