Bearing numbers
The bearing number fixes the size, so the same number fits whatever the brand. In 60xx, 62xx and 68xx bearings the last two digits give the bore: 00 = 10 mm, 01 = 12, 02 = 15, 03 = 17, and from 04 up multiply by 5 (6204 = 20 mm bore).
Seal suffixes
Open = no seal. Z = one metal shield; 2Z or ZZ = shields on both sides. 2RS = rubber seals on both sides (best against dust and washdown).
