Most Brother sewing machines use the Class 15 or SA156 bobbins, which means most models can use this bobbin size. However, it’s worth noting that you need the specific bobbin for Brother and do not use anything as an alternative to avoid issues.
Some might say that you can use a Class 14 bobbin if you can’t find a Class 15 bobbin for your sewing machine. However, even using any generic Class 15 bobbin is not a good idea since not all Class 15 bobbins are the same, so why try a Class 14?

- Bobbins which are 0.910 inches in diameter and 0.350 inches high are called the style L bobbin
- Bobbins which are 0.910 inches in diameter and 0.310 inches high are called the Class 66 bobbins

Are Brother Bobbins Universal?
Brother bobbins are not universal, but no bobbin is universal, to begin with. There are various sewing machines in the market, which means you must use the specific one recommended by the manufacturer.
Does it matter what bobbin I use?
It’s crucial to use the correct bobbin for your sewing machine. Bobbins differ not just in size, but you can also find metal and plastic bobbins, whichever is recommended in your model.
Why is using the specific bobbin necessary? Bobbins are never universal or interchangeable.
For example, using the wrong size can affect stitch formation. Even switching between plastic and metal bobbins can affect the tension.

Types of bobbin
- Class 15 bobbins are the most common type, with flat tops and bottoms made of either metal or plastic
- M Class bobbins have bigger diameters than others because it is often used for industrial sewing machines
- L Class bobbins can be somewhat universal since you can use them on front-loading and drop-in style machines
- Class 66 bobbins are the opposite of L Class bobbins because you can only use them on top-loading machines
Are plastic bobbins better than metal?
Selecting between plastic and metal bobbins depends on your sewing machine. If your model is plastic, then a plastic bobbin is ideal, whereas a metal bobbin should be used on a metal sewing machine.
But of course, expect that metal bobbins are more durable. And if you’re using an older machine, you want something heavy like a metal bobbin instead of plastic ones that are more suitable for modern machines.
How to tell the bobbin size
- Consider the bobbin case dimensions
- Check the sewing machine class
- Identify the bobbin thickness
