Gammill Bobbin Winder O-Ring Large | On-Board Bobbin Winder Replacement

Keep your bobbin winding system operating smoothly with this Gammill Bobbin Winder O-Ring (Large), designed for newer-style Gammill quilting machines using the approximately 1.5-inch O-ring mounted on the back side of the bobbin winder plate.

This replacement O-ring helps maintain proper traction and smooth bobbin winding performance by ensuring consistent contact within the bobbin winder assembly. Over time, the original O-ring can become worn, stretched, cracked, hardened, or lose grip, causing slipping, inconsistent winding, or reduced bobbin winding performance.

Replacing the bobbin winder O-ring is one of the easiest and most affordable maintenance items you can perform to help keep your Gammill quilting machine operating reliably and efficiently.

Whether you are servicing your machine for preventative maintenance or fixing bobbin winding issues, this large replacement O-ring is an essential part to keep on hand.
