Horizontal Bobbin Case SINGER (Ref. 416397501)

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

This original replacement part immediately solves these problems, ensuring perfect thread glide. Its top-loading design makes it easy to insert the bobbin.

Important notice: Although the plastic mould is shared with other references, the spring and the metallic tension plate of this reference 416397501 are structurally specific and optimized for more advanced Singer electronic machines. Visually compare the metal plate of your old bobbin case with the photo of this product before ordering.

Note: The part shipped may or may not have felt, even if this detail does not exactly match the advertisement photo.
