BERNINA Small Spool Disk (2 Pack)

The BERNINA Small Spool Disk (2 Pack) is a simple but essential accessory for any BERNINA sewing, quilting, or embroidery machine owner. Measuring 0.5 inches wide, this small spool disk is designed for the smallest thread spools and ensures thread feeds smoothly and cleanly into your machine without friction or resistance. Using the correct spool disk prevents thread from rubbing against the spool itself, reducing tension irregularities that can lead to skipped stitches, thread breaks, and uneven seams.

This is a genuine, original BERNINA part. Using OEM spool disks ensures the correct fit and performance for your specific machine and thread spools.

Which BERNINA machines is this spool disk compatible with?

The BERNINA Small Spool Disk is compatible with all BERNINA sewing, quilting, and embroidery machine models. If you are unsure which spool disk size is right for your spools, the OSP Machines team is happy to assist.

Why do I need a spool disk — can I just sew without one?

Sewing without a spool disk can cause the thread to rub against the spool itself as it unwinds, creating extra friction and uneven pre-tension before the thread reaches your machine's tension system. This can result in skipped stitches, thread breakage, and inconsistent stitch quality. Over time, it can also cause premature wear on your machine's threading components.
