BERNINA Rotary Hook Bobbin Case for Embroidery with Golden Flap

The BERNINA Rotary Hook Bobbin Case with Golden Flap is a genuine BERNINA replacement and spare bobbin case designed specifically for embroidery use on BERNINA machines equipped with the 9mm rotary hook system.

Frequently Asked Questions

What is the difference between the golden flap bobbin case and a standard BERNINA bobbin case?

The golden flap on this bobbin case is a visual indicator that it is calibrated with slightly reduced lower thread tension, which is optimized for machine embroidery. A standard bobbin case is set for general sewing tension. Using the correct case for each task helps produce better stitch quality and reduces thread breakage.

Do I need a separate bobbin case for embroidery, or can I use my regular one?

While it is technically possible to embroider with a standard bobbin case, BERNINA recommends using a dedicated embroidery bobbin case with a golden flap for best results. Embroidery involves high stitch counts and different thread types, and the golden flap case is tuned to handle those demands. It also preserves your everyday bobbin case from additional wear.

Which BERNINA machines is this bobbin case compatible with?

This bobbin case is designed for BERNINA machines that use the 9mm rotary hook system, including the BERNINA 1000, 1000S, 1000UP, 1001UP, 1070, 1630, artista 180, artista 185, aurora, 435, 450, 640, artista 200, 730, 560, and 580. If you are unsure whether your machine uses the 9mm rotary hook, the OSP Machines support team can help you confirm compatibility.

Is this a genuine BERNINA part?

Yes. This is an authentic OEM BERNINA bobbin case, not an aftermarket copy. Genuine parts are manufactured to BERNINA's precise specifications to ensure proper fit and reliable performance in your machine.
