Sewing-machine bobbins and bobbin cases

A bobbin holds thread; a bobbin case supports it in some loading systems. They are separate parts, so a bobbin match does not prove bobbin-case compatibility.

Fit depends on the exact machine model. Use your machine details to compare parts and retailer listings before ordering.

What decides whether it fits

Bobbin class, exact height and top profile
Plastic or metal construction and the manufacturer’s stated material
Top drop-in, front-load or side-load system; bobbin cases require their own exact reference

What to check before buying

Full machine model, every suffix and sales region
Loading system and the code printed in the manual
Existing bobbin dimensions and material without treating appearance as proof

Before you order

What to check before buying

Never replace a specified plastic bobbin with a similar-looking metal version. Height or profile differences can affect stitch formation and the hook area.
