Using the right bobbin not only enhances your sewing quality but also protects your machine from potential issues.
What is a Bobbin?
A bobbin is a small spool that holds the lower thread in a sewing machine. Together with the upper thread, it creates a lockstitch. Bobbins come in various sizes and materials, tailored to fit specific sewing machines.

The Specific Bobbin for the DDL-87997
The Juki DDL-87997 uses a Class 15 bobbin. This bobbin is often made of metal and is specifically designed to fit this machine’s bobbin case snugly. Its precise dimensions and durability make it ideal for handling high-speed stitching without causing jams or uneven tension.

How to Identify Compatible Bobbins
To identify compatible bobbins:
