Collection: Sewing Machine Bobbins

The wrong bobbin can cause tension problems, skipped stitches, thread jams and noise, and it can damage the bobbin case. Bobbins come in different classes and sizes that are not interchangeable, so always use the type your machine's manual specifies.

Check your instruction manual, which lists the bobbin class or part number. SINGER® machines use classes such as Class 15, 15J and 66. Most modern PFAFF® sewing and embroidery machines use the same clear plastic bobbin (part #820921096). For HUSQVARNA® VIKING® machines, your manual or a dealer can confirm the right one.

A Class 15 bobbin is flat on the top and bottom. A Class 15J bobbin has a slight curve on one side and is a little shorter. They look similar but are not interchangeable, so use the class your machine requires.

Only if your machine is designed for it. Machines with a top drop-in bobbin and thread sensors, including many computerized and HUSQVARNA® VIKING® models, need plastic bobbins. Metal bobbins can interfere with the thread sensor and tension.

The green color is a trademark that identifies genuine HUSQVARNA® VIKING® bobbins, which are made to the exact specifications of the machine. Using the genuine bobbin helps keep tension even and works with the thread sensors on many models. Check your manual for the right bobbin type for your model.

Yes. Winding several bobbins in the colors you need lets you keep sewing without stopping to rewind, which is especially helpful for embroidery, quilting and long seams. Store wound bobbins in a case or on a holder so the thread does not unravel, and label them if you use several colors.

Pre-wound bobbins come already wound with thread, so you can drop them into the machine. They are convenient for embroidery and large projects, hold more thread per bobbin than hand-wound ones, and are wound evenly. Make sure the size matches your machine.
