SINGER Bobbin Case (Ref. 416489001)

The bobbin case is the essential part where the bobbin is inserted, ensuring perfect control of the lower thread tension during sewing. When this plastic holder wears out — such as small scratches, punctures, or nicks caused by the impact of a broken needle — the thread begins to snag or break, resulting in irregular and skipped stitches.

This original replacement part immediately solves these problems, ensuring the perfect glide of the thread.

Important notice: Please confirm that the shape of your old bobbin case and the metal tension plate match this image before ordering.
