Crankshaft bearings

Hello everybody...

At the moment I am in process of rebuilding PK 125 engine...

I found something that confuses me a bit

The both crankshaft bearings are the same dimension but they have different number markings on them

One have "6303" and the other one have "6204"...

What is the difference?

And which one goes where?

On what side of crankshaft?

Thanks

What was it?

I found the difference now...
