Hook & Bobbin Case for Bernina 217, 840, 940 and 950 (Compatible)

Replacement hook for Bernina 217, 840, 940 and 950. The fitment below is taken from the distributor's own listing for this part. It is a compatible (aftermarket) part, not a manufacturer-original part.

This list comes from the distributor's listing for this part. If your model is not named, do not assume it fits — check the part you are removing against the specification below, or ask us with your model number before ordering.

What this part does

The hook (rotary hook or shuttle hook) is the rotating or oscillating part that catches the needle thread and carries it around the bobbin to form the stitch. The hook point is finely ground; a needle strike that nicks it causes skipped stitches and shredded thread until the hook is replaced.

Specifications

How to tell if this is the right one

Hooks are model-specific. Use the model list exactly. Industrial hooks are also specified by rotation and bobbin size.

Signs you need this part

Skipped stitches that persist with a new needle and correct threading, thread shredding, a burr you can feel on the hook point, or the bobbin case will not seat.

Fitting it

Fitting a hook requires setting hook-to-needle timing and clearance. A technician job on most household machines; experienced industrial operators replace them routinely.

Questions about this part

Does this hook fit the Bernina 217?

Yes. The Bernina 217 is on the distributor's fitment list for this part, along with 840, 940 and 950. If your model is not listed on this page, send us the model number and we will check before you order.

Is this the original Bernina part?

No — it is a compatible aftermarket part made to fit the models listed. It is not a manufacturer-original part.

Can I stone the burr out?

A very light burr can be polished with a fine stone. If the point is visibly damaged, replace the hook — a polished-down point does not catch the thread loop reliably.
