bearing numbers

[duaneb]

I always thought that the numbers on bearings were a part # fron the company that made them, until today, now Im not sure.
Developed growl in the front of my GT. Upon investigation I found a bad wheel bearing. The bearings I removed say Timnken made in France so they are probably the origionals. Too late to call OGTS so off to NAPA I go. Yup they got em. 41$ for all 4. When I get them home bearings say SKF with exactly the same #s. Did SKF buy Timnken and keep the same numbering system or are the numbers on bearings standerized and mean the same thing no matter what brand you buy ?
The whole thing made me THINK and now my head hurts
Anybody know the answer?

I foound this to be true on all bearings regardless who the maker is. Usually the same amount of numbers that has to do with OD and ID, along with depth. But I could be wrong.

The inner & outer front wheel bearings for the 69 & later Opels with front disc brakes use A1 and A4 bearings. Most manufacturers use these part #'s. I'm not sure what the earlier pre-GT opels used without looking them up in my books.

The good thing about them is that they should always be available at any parts store since they are also the bearings used on the sixties Ford Mustangs with a six cylinder. They are also used on many other cars in the 60's & 70's.

The numbers are standardized so as long as you have the bearing number it can be looked up.
