👉 The Class 15 Bobbin

When it comes to bobbins, the Class 15 is one of the most common types you'll come across. This bobbin is about the size of an American nickel, with a completely flat design. It measures approximately 11.7 millimeters in width, which is just a little bit under half an inch. The Class 15 bobbin is available in both metal and plastic variants.

👉 The L Style Bobbin

Similar in size to the Class 15 bobbin, the L style bobbin is also about the size of a U.S. nickel, but with a flat design on both sides. The main difference lies in the width, with the L style bobbin measuring about 8.9 millimeters. While Class 15 bobbins can be used in machines that accommodate L style bobbins, the reverse is not possible. L style bobbins come in plastic, aluminum, and magnetic core variations.

👉 The M Style Bobbin

Another common type of bobbin is the M style bobbin. It has a distinctive size, similar to that of an American quarter, and measures 10.7 millimeters in width. Like the Class 15 and L style bobbins, the M style bobbin is completely flat. It is available in both metal and magnetic core versions.

👉 Metal vs. Plastic Bobbins

When it comes to the choice between metal and plastic bobbins, both options perform well. Some individuals may prefer metal bobbins because they perceive plastic bobbins to be of lower quality. However, this is generally not the case. Metal and plastic bobbins both function effectively and can be used interchangeably in most machines.

👉 Aluminum Bobbins

Aluminum bobbins, also known as quick line bobbins, are an alternative to metal and plastic bobbins. They offer the same level of performance but with the added advantage of faster winding due to their lighter weight. Like the other types, aluminum bobbins come in various sizes and are suitable for different sewing machines.

👉 Fill Tech Cores

Fill tech cores are pre-wound bobbins that are disposable or recyclable, depending on your preference. These cores are inserted into a bobbin case after removing the backlash spring. They are convenient and make bobbin replacement quick and easy.

👉 Honorable Mentions

In addition to the Class 15, L style, and M style bobbins, there are a few other notable mentions worth exploring.

1. Singer 163131 Bobbin: This unique bobbin, used in old Singer Touchinfo machines, features lines indicating thread yardage. It can be unscrewed to remove unwanted thread and is available only in plastic.

3. Class 15J Bobbin: Similar in size to the Class 15, the Class 15J bobbin has slight curved sides that differentiate it. It should not be used in machines designed for Class 15 bobbins.

4. Class 66 Bobbin: Also resembling the Class 15, the Class 66 bobbin has curved sides. This bobbin is not compatible with Class 15 machines.

5. Bernina 0115367000 Bobbin: This Bernina exclusive bobbin features a crosshatch pattern on the barrel and fits most older Bernina machines. Different variations of this bobbin are available.
