Different SKF bearing codes indicate different type of bearing. While each manufacturer uses their own bearing part numbers, there are a few numbers that could be considered standard in the industry.

If the first digit is a number, however, it is a metric bearing, and the second digit is the series, which reflects the robustness of the bearing. The series are, from lightest to heaviest:
8- Extra thin section;  9– Very thin section;  0– Extra light
1–Extra light thrust;  2– Light,  3– Medium;  4– Heavy

The third and fourth digits indicate the bore size in millimeters. Except for 0 through 3, the bore size is simply five times the third and fourth digits together. o through 3, however, are different:
00-10mm   01–12mm   02–15mm   03–17mm

If there is no fourth digit – for example, a 608 bearing, a common roller skate bearing – then the size is the last digit in millimeters. The last letters indicate something special about the bearing. For example:

Z- Single shielded;   ZZ- Double shielded;   RS- Single sealed;  2RS- Double sealed; V- Single non-contact seal;  VV- Double non-contact seal; DDU- Double contact seals; NR- Snap ring and groove; M- Brass cage
