Ball Bearing
How the Size for ball bearing is calculated?
What shows the 6305 for skf make ball bearing?
Personally, I look it up in a catalog. The number does have meaning, it is not arbitrary. For your 6305, the 6 means single row deep groove, the 3 is the “diameter series” I don’t quite understand what that means, I assume it has something to do with how the outside diameter is related to the inside diameter, the 05 is the code for the inside diameter, in this case, the diameter in mm divided by 5, or a 25mm bore.
The first link in “sources” below is quite informative.
