Hello,
I've heard a few things in the past that don't seem to fit well together in my mind, and I was hoping that someone could clear up this mystery for me.
1) sputter bearings, like those commonly used at the crankpins in many engines, have higher fatigue limits than other bearing materials for the same application, and can tolerate higher specific loads
2) these bearings have a harder exposed surface
3) these bearings are more resistant to siezure
4) these bearings can tolerate lower minimum oil film thicknesses
To me it seems that #3 and #2 don't fit well together. #1 and #2 do seem to fit together well. #4 seems to fit with #3. How can sputter bearings do all four, if they can indeed?
