SINGER Horizontal Bobbin Case (Ref. 314662001)

The horizontal 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 a broken needle impact — the thread begins to snag, loop underneath, or break, resulting in irregular and skipped stitches.

This original replacement part immediately solves these problems, restoring perfect thread glide to your machine. This is a very specific bobbin case, designed to fit the rotary hook system of the more robust vintage SINGER machines (commonly known as the Centaur series).

Important notice: The shape of this bobbin case has very unique openings and cutouts in the outer plastic. Please confirm that the shape of your old bobbin case exactly matches this image before ordering.
