main journals
Bearing journals.
That usually refers to the part of a standard transmission that inserts into the crankshaft pilot bearing or bushing.
You have rod bearing caps that hold the rods on the crankshaft. And you also have main bearing caps that hold the crankshaft in the engine block. NEUTZ.
Main Journals
When rod bearing clearance is too tight the end result is what is called a spun bearing -- definitely a bad thing. Bearing clearance is the difference between the inside diameter of the bearing and the outside diameter of the crankshaft journal to which it is clamped. The bearing is supplied pressurized oil fed by the oil pump, it should never touch the crankshaft journal but should always float on a wedge of oil. If the clearance is too tight the bearing touches or drags on the crankshaft journal and the journal grabs the bearing and spins it inside the housing into which it is clamped -- which in the case of a rod bearing is the big end of the connecting rod. Once this happens it all pretty much self destructs as it chews up the big end of the connecting rod and the crankshaft journal as well.

Interference between journal bearing to bearing housing is called bearing crush.
A flower bearing leaf is called a bract.
If the only damage done by the thrown rod bearing is that the crankshaft has become scored at that bearing's location (called a journal), you might be able to get away with having that particular crankshaft journal turned ("turned" here means to have the crankshaft reground and polished to smooth out scratches caused by the thrown rod bearing), as well as replacing the bad rod bearings with oversized (thicker) ones at the journals that were reground, to compensate for the slightly smaller diameter of the reground journals, but often more damage has also been done (bent or broken piston rod, damage to the piston and/or chamber at that location, etc.), requiring more repair or a replacement engine. But it's worth dropping the oil pan to have a look at the damage--you could get lucky.
The process is called Genetic Modification
The spore-bearing structure of a club fungus is called basidiumm.
Historically, Southerners who supported reconstruction were often called scalawags.
