Most ball bearings are metric sizes. There is an inch series, but metric is more common.

Timken moved from Ohio to ChiCom in 2004. Dunno about the Swedes.

I'm using a 30x48 lip seal on the front of the crankshaft.

Quite frankly I use 100's of bearing a month most all from China. I have had little, well no problems. Now we are talking about alternators, power and steering motors, etc.
I did have issues with FAG bearings a few decades back. Big fan of Japanese bearings now gone.

SKF has always aimed to be international in both sales and manufacturing - they had 12 manufacturing facilities worldwide in 1930, the largest in Philadelphia, PA. Now they have 100 manufacturing sites in 70 countries according to Wikipedia.

Almost all bearings are metric.

i think Timken has manufacturing centers around the world, they say the headquarters are still in dayton.

but i believe they still offer American and German made products.

its not that i dont think the chinese are capable, i just proudly use American made products.

one day i hope to see industry restored in America

I am lucky with the metric bearings easy for us to buy new ones .

The crank shaft to cam shaft distance on the T is supposed to be between 3.9367 to 3.9376 inches, which curiously enough is 99.99 to 100.01 millimeters. Someone in the experimental room at the Piquette Avenue plant must have been used to millimeters.. Hungrarian immigrants Joseph Galamb or Eugene Farkas perhaps?

wierd, happens today and it happened back then i guess.

i looked into Timken and they have closed down one of their manufacturing plants in ohio, but they still have lots of locations in the US. i dont know if they make anything here though.

I guess when all the industry is in China, you go to China. sad but it makes sense.

and apparently Timken makes their own steel for their bearings.

The finest pre 1900 ball and roller bearings were made in Europe ( England,France and Germany) and many were imported to the US. When the S.A.E. ( Society of Automotive Engineers) standardized so many things (one was threads that we are familiar with) they standardized bearings by using inch equivalents of commonly used metric bearings. So today when you look at a bearing catalog so many of the dimensions are in odd thousandths of an inch but their origin is a nice even metric number. To you speedster guys, the shaft height above the base on a high tension magneto is a metric number. The SAE standardized an inch equivalent since so many magnetos were coming from and originated in Europe ( Simms, Bosch, Splitdorf, Eisemann, etc.).

Timken still has steel mills in Canton, Ohio. I work two shutdowns at two plant last year. I do not know what they make at one but the other makes steel bars. I live near Dayton and they have no places here.

The world has seen very few tires that were not in inches. There was a 400 mm tire for Citroen and some Alfas but most rims are measured in inches.
Spark plugs are metric, have been since Christ was a lad, I guess with the exception of the T with its pipe threads.
Since 1937 Ford has used 14mm spark plugs,
Bearings are mostly metric as are tumors.

Aaron,

I think Model A Ford and 28 Chevrolet spark plugs were 7/8-18 US fine threads.

7/8 18 is a very common plug thread among vintage or large engines.
