Thread Tension Assembly regulates the amount of resistance applied to the needle thread as it moves toward the fabric. Turning the plastic cap adjusts the internal tension spring, tightening or loosening the upper thread to achieve well-balanced, high-quality stitches. This is a highly versatile standard part used across multiple generations of Juki industrial flat-bed sewing machines and their clones.
