IIRC, typically RS= Radial Shield, 2RS=Radial shielded both sides.....
( uncommon to shield only one side, and since it's easy enough to remove
shield(s) if desired anyways )...
The 6203 is very common, and therefore a relatively inexpensive item,
basically it's being your garden variety standard metric radial ball bearing
design and having many, many applications in small electric motors,
automotive alternators and so on.......
This particular bearing will have a 17mm bore with 40mm outside dimension,
and it will be 12mm wide...
