BERNINA Metal Bobbin for CB Hook Machines
Keep the correct bobbin ready for your compatible BERNINA sewing machine with this individual metal bobbin for the CB Hook System. It is designed to work with the matching CB-hook bobbin case used by selected 5.5 mm BERNINA machines, including many activa, virtuosa, 3 Series and earlier-generation models.
An extra bobbin is a simple way to keep frequently used thread colours prepared, move between projects more efficiently or replace a bobbin that has become bent or damaged. Because BERNINA machines use several different hook and bobbin systems, confirming your machine model and hook type before ordering is essential.
- Individual metal bobbin for compatible BERNINA CB Hook machines
- For the traditional BERNINA CB Hook System used on selected 5.5 mm machines
- Suitable for sewing and embroidery where supported by the compatible machine
- Useful as a spare or for preparing multiple thread colours
- Bobbin case is not included

BERNINA CB Hook compatibility guide
This bobbin is intended only for machines equipped with the BERNINA CB Hook System. The following compatibility is based on BERNINA’s accessory and machine documentation. Model names can be reused across different machine generations, so the hook system is more important than the number alone.
BERNINA activa and 3 Series
- activa 125, 125 S, 130, 135, 135 S, 140, 145 and 145 S
- activa 210, 220, 230, 230 PE and 240
- B 215
- B 325, B 330, B 335, B 350 PE and B 380
BERNINA virtuosa

BERNINA artista and aurora

- B 555
- Earlier-generation B 570 QE with the CB Hook System
Selected earlier BERNINA models
- 910, 930, 931, 932 and 933

Important: compatibility should not be determined by stitch width or the BERNINA name alone. BERNINA also makes rotary-hook and BERNINA Hook bobbins that are not interchangeable with this CB-hook bobbin.
Models that require extra checking
BERNINA 570 QE
The model number 570 QE has been used for different generations. This metal bobbin suits the earlier-generation 5.5 mm B 570 QE equipped with a CB Hook. It does not suit the later-generation 9 mm B 570 QE fitted with the BERNINA Hook and jumbo bobbin. Check your manual, existing bobbin or full model generation before ordering.
BERNINA aurora
Not every aurora model uses the same bobbin. The aurora 430 and 440 QE use the CB-hook bobbin listed here. Models such as the aurora 435 and 450 use a different rotary-hook bobbin. If your machine has a rotary hook, see the BERNINA Metal Bobbin for Rotary Hook Machines .
Current BERNINA Hook machines
Many newer BERNINA 4, 5 and 7 Series machines use the larger BERNINA Hook bobbin rather than this metal CB bobbin. A current machine having a maximum 5.5 mm stitch width does not automatically mean it has a CB hook.
What is included?
- One BERNINA metal CB-hook bobbin
This listing does not include thread, a bobbin case, storage box or other machine accessories. If the case itself needs replacing, view the matching BERNINA Standard CB Bobbin Case and confirm its model list before purchase.
Why keep spare bobbins?
- Prepare regular colours: keep commonly used neutral, quilting or embroidery threads ready to load.
- Reduce project changeover time: switch thread without immediately unwinding another bobbin.
- Separate thread types: organise bobbins by fibre, colour or intended project.
- Replace damaged bobbins: a bent, rough or damaged bobbin should not be forced into the bobbin case.
- Build a machine-specific set: avoid accidentally mixing CB-hook bobbins with rotary-hook or jumbo bobbins.
Choosing the correct BERNINA bobbin
Before ordering, check the model identification on your machine and consult its manual for the stated hook system. Compare the product with the correctly identified bobbins already supplied for the machine, but do not rely on appearance alone—different BERNINA bobbins can look similar while being intended for different hook mechanisms.
If your model is not shown above, browse the full range of BERNINA accessories at Two Petals or contact the Two Petals team with the complete model name. For models such as the 570 QE, include the machine generation or a clear photograph of the existing bobbin and hook area.
Frequently asked questions
Is this a bobbin or a bobbin case?
This product is one individual metal bobbin. It sits inside the compatible CB bobbin case, which is a separate part and is not included.
Is the bobbin supplied with thread?
No. It is an empty bobbin ready to be wound using your compatible BERNINA machine’s bobbin-winding system.
Will this fit every BERNINA sewing machine?
No. It is specifically for compatible BERNINA CB Hook machines. BERNINA rotary-hook, B9 Hook, BERNINA Hook, longarm and other bobbin systems require their corresponding bobbins.
Does it fit every BERNINA 3 Series machine?
It fits the documented CB-hook 3 Series models, including the B 325, B 330, B 335, B 350 PE and B 380. If a future or unfamiliar model carries a similar series name, confirm its hook system rather than relying only on the series number.
Does this bobbin fit the BERNINA 570 QE?
Only the earlier-generation B 570 QE that uses the 5.5 mm CB Hook System. The later 9 mm B 570 QE uses the BERNINA Hook and a different jumbo bobbin.
Will it fit a BERNINA aurora 450?
No. The aurora 450 uses a rotary-hook bobbin. This CB-hook version is intended for documented aurora 430 and 440 QE machines.
Can I use it for machine embroidery?
BERNINA identifies the CB-hook bobbin for sewing and embroidery. Embroidery use still depends on the capabilities of your compatible machine, the correct CB bobbin case and the thread and setup specified in your machine manual.
Why should I avoid mixing different BERNINA bobbins?
Each BERNINA hook system has a matching bobbin and bobbin case. Using the correct type helps ensure that the bobbin sits, winds and turns as intended within that hook system. Keep CB, rotary and jumbo bobbins stored separately to prevent mix-ups.
What should I do if my model is not listed?
Do not select a bobbin based only on its colour, material or general shape. Check the machine manual or ask Two Petals to confirm compatibility using the complete model name and, where relevant, the machine generation.
Buying summary
Choose this BERNINA Metal Bobbin for CB Hook Machines when you need an individual spare or replacement bobbin for a verified CB-hook model. It is a practical addition for dressmaking, patchwork, quilting, decorative sewing and supported embroidery, particularly when you like to keep several thread colours ready to use.
