Welcome to our comprehensive guide on sewing machine bobbins. In this article, we will delve into the importance of this small yet crucial part of a sewing machine. Whether you are a beginner or an experienced sewist, understanding the role and types of bobbins is essential for achieving high-quality stitches. So, let's dive in and explore everything you need to know about sewing machine bobbins.
What Is a Bobbin?
A bobbin is a cylindrical-shaped component that holds the thread used for stitching. It can be made of wood, metal, or plastic, with each sewing machine model having its own specific bobbin material The bobbin can be easily removed from the machine, allowing you to fill it with thread separately. However, some sewists prefer to thread the bobbin directly using the sewing machine for convenience. It is worth noting that manually threading the bobbin can be time-consuming.
Bobbin Shapes & Styles
Sewing machine bobbins come in various sizes and styles. The size of a bobbin can be determined by its thickness, and different sewing machine models may require specific bobbin sizes. Let's take a closer look at some of the basic types of sewing machine bobbins:
-
The L-Bobbin: This small bobbin has a diameter of 0.91 inches and a length of 0.35 inches. It is ideal for smaller sewing machines.
-
The M-Bobbin: The M-bobbin is used in larger sewing machines capable of stitching thick fabrics like canvas. It measures 1d inches in diameter and has a length of 0.430 inches.
-
66 Class Bobbins: The 66 class bobbin shares the same diameter as the L-style bobbin but has a shorter length of 0.31 inches.
-
Class 15 A Style Bobbins: Class 15 A-style bobbins have varying dimensions depending on the sewing machine brand. They are generally larger in size compared to other bobbin types.
Understanding the specific bobbin type and size required for your sewing machine is crucial for optimal performance and stitch quality.
How to Insert a Bobbin Case in a Singer Sewing Machine
Inserting a bobbin case in a Singer sewing machine is a relatively simple process. Here's a step-by-step guide to help you:
- Keep the thread in the spool and transfer it to the spool rim to avoid any threading hassles.
- Push the bobbin device to the left side and fix it into the correct position.
- Hold the thread and firmly press the controller to thread the bobbin.

Plastic Bobbin or Metal Bobbin – Which Type to Choose?
When it comes to choosing between plastic and metal bobbins, there are a few factors to consider. Let's explore the characteristics of each type:
Plastic Bobbins: Plastic bobbins are commonly found in older sewing machines. While they are lightweight and work efficiently with modern machines, they may not be as durable as metal bobbins. Over time, plastic bobbins can become loose and affect the smooth operation of the sewing machine.
Metal Bobbins: Metal bobbins, on the other hand, are known for their durability and longevity. They do not loosen up over time and provide stable thread tension. The weight of metal bobbins also contributes to their superior performance. However, it's important to ensure that your sewing machine is compatible with metal bobbins before using them.
Consider the specific requirements of your sewing machine and choose the bobbin material that best suits your needs.
Replacing Sewing Bobbins
The process of replacing sewing bobbins may vary depending on the sewing machine model. Here's a general guide to help you replace a bobbin:
- Eliminate the current bobbin by pressing the right button, causing it to pop up.
- Rotate the bobbin in an anti-clockwise direction to remove the thread from the bobbin.
- Gently remove the bobbin from the machine.
- Insert a new bobbin into the designated space, ensuring it is securely in place.
Always refer to your sewing machine manual for specific instructions on replacing bobbins.
Where Can You Place the Bobbin Case in a Sewing Machine?
The placement of the bobbin case in a sewing machine can vary depending on the machine's design. There are two common methods of loading bobbin cases:
-
Front Bobbin Case Loading: This method involves loading the bobbin case from the front of the machine. The bobbin will be facing towards you, allowing for easy access and monitoring.
-
Side Bobbin Case Loading: Some machines feature side bobbin case loading, which is less common. The bobbin case is loaded from the side, and the casing may not be compatible with other types of machines.
The size of the hole on the machine differs between front and side bobbin case loading methods. Refer to your sewing machine manual to determine the appropriate placement for the bobbin case.
Are Bobbins Interchangeable or Universal?
Contrary to popular belief, bobbins are neither interchangeable nor universal. It is essential to use the appropriate bobbin for each sewing machine to ensure smooth operation and stitch quality. Even minor differences in bobbin size can cause issues with your sewing machine.
When selecting a bobbin, consider the recommendations provided by the sewing machine manufacturer. The manual of your sewing machine will provide guidance on the best type and size of bobbin to use.
