Bearing Preload | National Precision Bearings
The purpose of preload in a bearing system is to eliminate clearance that is designed into standard ball bearings. Almost all radial ball bearings are made with a clearance or space between their components to allow for free movement.

Main Bearing Clearance issue
No, that means the crankshaft is "undersize" from a standard nominal size, like it was ground .011" undersize when it should have been .010" under....or a standard size that was polished .001" under and a "standard" size bearing would then have too much clearance.....in that last case then you would use the .001" undersize bearing.

Bearing Clearance W/Coated Bearing | Yellow Bullet Forums
I use coated bearings in my stuff. I set the clearance to something "safe", say like .003" on a 2.5" main journal, and then coat the bearings and put them in. The coating will reduce the clearance so oil pressure doesn't take too much of a hit, but will wear away if the bearing needs more. It will eventually find a happy medium.
