Genuine Seiko Large Capacity Bobbin (Part #BO1215MMN)
Maximize your sewing efficiency with the Genuine Seiko Large Capacity Bobbin (Part #BO1215MMN). This authentic "M-Style" equivalent component is engineered specifically for the oversized rotary hooks used in the Seiko LSW long-arm series.
In the world of long-arm industrial sewing—where you are often stitching several continuous feet of heavy upholstery, automotive covers, or sails—bobbin capacity is king. The BO1215MMN is designed to hold nearly double the thread of a standard Class 15 bobbin. This significantly reduces the frequency of bobbin changes, preventing the need to restart a seam in the middle of a visible topstitch—a common cause of structural weakness and aesthetic flaws in heavy-duty work.
