Frequently Asked Questions

How do I know if my BERNINA machine uses the CB hook system?

BERNINA machines use different hook systems depending on the model and series. The CB (Central Bobbin) hook system is used on a wide range of BERNINA models including activa, virtuosa, aurora, artista, and many numbered series machines. Check your machine's manual or the compatible models list on this page. If you are unsure, the OSP Machines support team is happy to help you confirm the correct bobbin for your machine.

Can I use generic or off-brand bobbins in my BERNINA CB hook machine?

BERNINA recommends using only genuine OEM bobbins in their machines. Even small variations in bobbin dimensions or weight can affect thread tension, cause skipped stitches, or accelerate wear on the bobbin case. These are genuine BERNINA bobbins manufactured to factory specifications, making them the safest choice for your machine.

Are these bobbins compatible with BERNINA embroidery and bobbinwork applications?

Yes. These CB hook bobbins are suitable for sewing, embroidery, and bobbinwork on all compatible BERNINA CB hook machines. They are the same OEM bobbins used across all of those applications.

Does OSP Machines provide any support with this purchase?

Yes. OSP Machines provides free support for the life of your machine to all customers. If you have questions about which bobbins are right for your machine or need any help, you can reach out to the OSP Machines team at any time.

Why buy a 5 pack instead of individual bobbins?

Having multiple bobbins pre-wound in different thread colors saves time during projects and means you are never caught mid-project with an empty bobbin. A 5 pack ensures you always have backups on hand, which is especially useful for embroidery and projects that use heavy thread consumption.
