For example, a 6204-2RS bearing has these characteristics:
6---: Single row deep groove bearing
-2--: Code for the robustness, light in this case (and just right for this duty; a 6304 medium duty bearing is 52mm OD and 15mm thick, too big for our wheels, and able to carry loads not seen on motorcycles).
--04: Code for the bore size in millimeters; five times the 3rd & 4th digits added, with exceptions. In this case 20 mm bore.
-2RS: The suffix tells something special about the bearings. In this case, two resilient seals that keep the long-life grease in and keep dirt and water out.
Notes on Ball Bearings

Note that all 6204 bearings will be the same size: 47 mm outside diameter, 20 mm inside diameter, and 14 mm thick. All bearings with the same industrial designation will be the same size--all 6203, etc. All brands will be interchangeable, and there are many top quality brands around the world. And some poor quality brands or no-brand bearings. The stock Suzuki bearings (which have Suzuki part numbers, not industry standard numbers) have a built-in seal on one side and a removable seal on the other side. The removable seal allows the opportunity to re-grease, and the opportunity to get dirt inside.

Besides not being true, this guy's a spammer.

All the bearing sizes and common part numbers may be found at What are the sizes & numbers of the important bearings?
