Most of the information used to create this program is from Machinery's Handbook,
except for the info on pressure/velocity.
The piston diameter and compression ratio is used to calculate the load on the bearing.
For a main bearing of .500 dia, a minimum oil groove of .030 wide, and .015 deep is suggested
Here are 2 PDF files that I found while searching for information on bearings. They have very little
info pertaining to engine design.
I don't remember where I got these files from, but I make them available here:
Bearing Design Guide (PDF)
Sleeve bearings (PDF)
NOTE: When using this program, please keep in mind that this is not a final word on bearings. This will help you to size your bearings, but there are many things in bearing design that are not addressed here. I made this for my own use and will not be responsible for your use (or mis-use) of it.
