how many rpm do you think a roller on the cam see's when the berg engine is flat out,
30,000 rpm?
30,000 rpm?
that would be 10,000 then
if the berg crank is revving at 10,000
the cam is doing 5,000
if it is a two to one between the cam and roller , this would see the rollers doing 10,000 rpm.

8O the cam to roller ratio is 0.6 to 1 :shock:
so at 10,000 crank revolutions the roller is seeing around 8,000 rpm.
that is a lot less rpm than i first thought
very low for a small bearing.

how long do these rollers tend to last ?
i know it depends on what oil you use but as a generalization from best to worst :?:
