Thread Tension Assembly is a spare part that plays a crucial role in the tension system of a sewing machine.
It is responsible for regulating the tension of the upper thread, which is the thread that is fed through the needle and forms the top stitches of a sewing project.
It contains a tension disc, tension spring, tension regulator, and other related parts.
When properly adjusted, it controls the amount of tension on the upper thread, allowing it to feed smoothly through the machine and create even and consistent stitches.
If this essential component becomes worn or damaged, it can cause the thread tension uneven or unstable, that lead to poor-quality stitching or even thread breakage. In such cases, it may be necessary to replace the Thread Tension Assembly with a new one.
