Fixya is unable to identify bobbin case sources.

Consult your owner's manual to find out what bobbin to use in your machine. There are many bobbins available, some will actually fit in your machine, but they may be a slight bit different size that will negatively affect your machine's operation. If you don't know which bobbin to buy, take the machine's manufacturer name and model to a sewing shop and ask if they can sell you the bobbin for your machine. Better yet, find a local dealer who supports your particular machine's manufacturer. You may even find the appropriate bobbin online by searching:
Manufacturer + Model + the word "bobbin"

if you have the original bobbin or one that is working, there are a limited number of generic bobbins that fit just about all makes and models
go to a service center for sewing machines ( any model) material shop, haberdashery as most have a selection of bobbins that will match yours
All you should need is the width and diameter to be the same

Hello
There are many bobbin styles which still measure as you have indicated, however they do not "fit" correctly resulting in poor to no stitching.

Your local reputable sewing machine retailer will be able to provide the correct bobbins for your sewing machine 'make' and 'model'.

Happy stitching.

Do you have an elna 7200? If so it uses class 15 bobbins part # 2518P. These are the most common bobbins in the household sewing machine market.

part number 1939 Looks like a normal bobbin winder friction ring. Try sew classic. they have some generic ones in a few different sizes. (btw.... looks like a Janome one might fit, but I didn't find it)

You need a bobbin like this:

You can puchase them from this link

Janome have one standard plastic bobbin that fits almost all their models except
1600P, 1600P-DB, 1600P-DBX and MB4.
So if you see packets of plastic "Janome" bobbins for sale they will be the right ones.

Is the metal spool just spinning in the middle of the bobbin because the hole is not a tight fit? I would check my manual for the correct bobbin & then purchase using the specific part number (e.g. SA156). I found this number in the list of "included accessories" for my machine. There will be a part number besides the name.
