Bobbin Nest SkyBlue for EverSewn

Replacement bobbin for EverSewn sewing machines — see the fit notes below for how to confirm it matches yours.

What this part does

The bobbin is the small spool that holds the lower thread. The needle thread loops around the bobbin thread on every stitch, so the bobbin's class, diameter and height have to match the bobbin case or hook the machine was built with. A bobbin that is a fraction of a millimeter too tall or too wide will bind, rattle or feed unevenly.

Specifications

How to tell if this is the right one

Bobbins are matched by class, not by brand name. Check your manual or the bobbin that came with the machine: class 15 (about 20 mm across and 11.5 mm tall) and class 66 (about 20 mm across and 9.5 mm tall) are the two most common household sizes, and plastic and metal versions of the same class are not always interchangeable in a given machine. If the listing names your machine model, that is the fitment the distributor records for it; if it only names a class, compare it with the bobbin you are replacing.

Signs you need this part

Thread nests under the fabric, clicking from the bobbin area, the bobbin spins on after you stop, or the bobbin will not seat flat in the case. Dented, cracked or burred bobbins should be discarded — they chew thread.

Fitting it

Wind bobbins evenly and not past the rim. Drop-in machines usually load with the thread coming off counter-clockwise; front-loading cases usually take it clockwise. Check the diagram on your machine or in the manual.

Questions about this part

Which machines does this bobbin fit?

The distributor's listing does not name specific models for this part, so we do not claim a fitment. Compare the specification on this page with the part you are replacing, or send us your machine's model number and we will check.

Can I use a plastic bobbin instead of a metal one?

Only if your machine is specified for it. Some machines with magnetic or sensor-based bobbin detection need the material they shipped with. If the listing names your model, the material shown is the one recorded for that machine.

How do I find my bobbin class?

Measure the bobbin you have: class 15 is about 20 mm across and 11.5 mm tall; class 66 is about 20 mm across and 9.5 mm tall; L-style bobbins are about 20 mm across and 9 mm tall. Your manual will also state it.
