20-Pack Bobbin Case Springs 22×16mm – JUKI SINGER BROTHER

20-Pack Metal Bobbin Case Springs – Universal Fit for Industrial Sewing Machines

Keep your sewing projects running smoothly with this set of 20 durable metal bobbin case springs. Designed to fit a wide range of industrial single-needle straight-stitch sewing machines — including JUKI, SINGER, CONSEW, and BROTHER models — these precision-engineered brake springs deliver consistent, light tension on your bobbin to keep thread feeding evenly from start to finish.

Each spring functions as a no-back-lash brake, applying gentle, constant pressure that causes bobbins to stop spinning faster whenever sewing operations pause. This prevents thread from unraveling or tangling inside the bobbin case, reducing skipped stitches, thread jams, and costly downtime — especially in high-volume embroidery or garment production environments.
