    Hello,

    I have been using an olive hole jewel bearing for my palet Arbor pivots. Does anyone have experience with straight hole (parallel) jewels? I get the feeling pivots may last longer with the straight holes. Olive hole theoretically offers less friction. My target is longevity.

    Thanks
