Ball bearings on plain

[George Dawson]

Ah, an explanation that makes sense.
Thanks
George


I'm not a current engineer (or really a current anything!) but I think 
the argument was that gudgeons running on plain bearings are (usually) 
supported much closer to the point of exit from the headstock - probably 
within half an inch or less, whereas the point of support in a ball 
bearing, not always obvious from the outside of the housing, can be an 
inch or even more, increasing the bending moment considerably.
