The centrally located coaxial cylindrical journal known as the main journal and the offset cylindrical crankpins known as the rod journal form the basic parts of the crankshaft.
The main journal rests on the block rotating about at a fixed point around the main bearing. The rod journal is connected to the connecting rod through the rod bearing and thus revolves as the connecting rod moves up and down.

Mainly there are two type of Journal in Crankshaft:
1) Main Journal.
2) Rod Journal.
Journal at the Connecting Rod End is called Rod Journal.
And space between each Rod journal which sit on the cylinder block is called Main Journal. It is attached with thrust bearing.
