AFBMA Bearing number interchange 1

[PAP]

Dear all
Anyone can help me about the resource of the AFBMA standard and Bearing number comparison between AFBMA standard and Manufacturer (such as SKF,etc ). (I found it on name plate of motor and think that why this standard is generated to confused many people ? What's standard purpose? )
Thanks very much.

AFBMA is a standard that identifies bearing dimensions. If you give AFBMA number to any bearing manufacturer, they will tell you their equivalent part number (if it exists).

SKF also uses a numbering system similar to several others.

As an example, AFBMA number 65BC03 cross references to SKF catalog number 6313 as follows:

1st 2 digits (65) in the AFBMA number is bore diameter in millimeters. Last 2 digits (13) in the catalog is bore diameter in millimeters divided by 5.

3 and 4th characters (BC) in the AFBMA number is type of bearing. BC stands for Conrad bearing. The first character (6) in catalog number identifies type of bearing (6 means Conrad).

5&6 characters in the AFMBA number is the dimension series. 02 is light duty (03 would be medium duty, 04 would be heavy duty). The 2nd character (2) in the catalog number identifies the dimension series. In this case catalog number uses the same character as AFBMA but only one character instead of 2 (2 instead of 02).

My last paragraph discussion corresponds to AFBMA 65BC02 or SKF cat 6213
