Very Interesting! I never knew of that Lifter! 350% More Load Bearing!?
Thanks for Posting This.
I think that you are 100% correct. It is a big advantage of this oilite type bearing and that is the weakness of the roller bearing. It does depend on the oilite material having the bearing (as in bearing the load) capacity necessary to take the load.
I've seen the roller (pin rollers) "cage" have problems as well.
The solid material will still tend to take the majority of the load at one point along the radius and will indicate overloading by cracking at that point. If it is too soft, it will just crumble.
There should be two engineering specs for the material determined by the manufacturers testing. Compression capacity and tensile (stretching) capacity. But you need to know the amount of the load being placed upon it.
In the case of the roller lifters that would have to be the spring pressure.
Bending capacity would generally be viewed as tensile strength that I am aware of.
