I think that with adequate lubrication, the inner race and 'fork' will not get sufficiently hot to melt the cam.
A couple of times now I have tipped my old Mark VII up to the left and put a small pool of oil in on the tiny bearing and left it sitting that way a day or two and the oil goes down some. It is staying quiet. I have also ran the unit at slow speed a minute while tipped up and the oil standing there.
I think we discussed doing that some time back?
I have not really been using it much at all but I want to keep it lubed there. It is supposed to be my semi-dedicated dado machine but I'm not getting in a lot of shop time now.
Maybe more this winter.
I do have a spare cam but hope I never need it...
I did not equip with Shopsmiths in spite of the setups but because of them.
