This part is essential for managing the movement of the bobbin case during the stitch cycle, ensuring smooth thread passage in high-speed industrial environments. The opener helps move the bobbin case slightly at the correct moment, allowing the upper thread loop to pass freely around the case to form a lockstitch.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePart Number: 224004\u003c\/li\u003e\n\u003cli\u003eType: Replacement (aftermarket)\u003c\/li\u003e\n\u003cli\u003eMaterial: Durable steel construction\u003c\/li\u003e\n\u003cli\u003eApplication: Industrial walking foot sewing machines\u003c\/li\u003e\n\u003cli\u003eFunction: Manages bobbin case movement during stitch cycle for smooth thread passage\u003c\/li\u003e\n\u003cli\u003eAssociated Parts: Works with mounting screw Part #200118\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eMachine Compatibility:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSinger Models:\u003c\/strong\u003e 111W class, 211W class (including 211G, 211U, 112W).

It performs two essential functions: \u003cstrong\u003eThread Clearance\u003c\/strong\u003e - The opener helps \"open\" or move the bobbin case slightly at the correct moment during the stitch cycle, allowing the upper thread loop to pass freely around the case to form a lockstitch. This precise timing is essential for proper stitch formation in high-speed industrial sewing. \u003cstrong\u003eStability\u003c\/strong\u003e - The opener works in conjunction with mounting screw (Part #200118) to remain securely positioned within the hook assembly, ensuring consistent performance even under the mechanical stress of continuous industrial operations.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFunction \u0026amp; Benefits:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis bobbin case opener is constructed from durable steel to withstand the mechanical stress and high-speed operation of industrial sewing machines. A worn, damaged, or missing bobbin case opener can cause thread jams, skipped stitches, or incomplete lockstitch formation, resulting in poor stitch quality and costly production interruptions. Replace a worn opener to restore proper bobbin case movement and ensure reliable, professional-quality stitches in heavy-duty industrial sewing applications.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eInstallation Note:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eInstall the bobbin case opener in the hook assembly, securing it with mounting screw Part #200118.
