This spring is characterized by its tapered beehive or conical shape, which allows it to provide consistent resistance as it is compressed by the tension nut.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePart Number: 125314\u003c\/li\u003e\n\u003cli\u003eType: Replacement (aftermarket)\u003c\/li\u003e\n\u003cli\u003eMaterial: Steel\u003c\/li\u003e\n\u003cli\u003eDesign: Tapered beehive\/conical shape\u003c\/li\u003e\n\u003cli\u003eFunction: Provides primary tension for upper thread in tension assembly\u003c\/li\u003e\n\u003cli\u003eAlternate Part Numbers: 45869, 13710\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMachine Compatibility:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eVintage Favorites:\u003c\/strong\u003e 15, 15-30, 15-91, 27, 28, 66, 99, 101, 115, 127, 128, 185, 192, 201, 206, 221 Featherweight, 222 Featherweight, 237, 239, 301, 301A, 306, 319, 327, 328, 329, 1200-1\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSlant-Needle Series:\u003c\/strong\u003e 401, 401A, 403, 403A, 404, 500 (Rocketeer), 500A, 503, 503A\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Function \u0026amp; Design:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe upper tension beehive spring is a core component of the upper tension assembly, assisting in keeping the thread aligned and at the proper pressure for balanced stitch formation. The spring's tapered beehive or conical shape allows it to provide consistent resistance as it is compressed by the tension nut, ensuring smooth, even thread tension throughout the sewing process. This consistent tension is essential for preventing thread breakage, skipped stitches, and uneven stitch formation. A worn, weakened, or damaged beehive spring can cause erratic thread tension, resulting in poor stitch quality and frustrating sewing interruptions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFunction \u0026amp; Benefits:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis beehive spring provides the primary tension regulation for the upper thread, working in conjunction with the tension discs and tension nut to control thread flow. The spring's unique conical design ensures that tension remains consistent even as the tension nut is adjusted, providing smooth, predictable tension control. Replace a worn or weakened beehive spring to restore proper upper thread tension and ensure balanced, professional-quality stitches.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInstallation Note:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eRemove the tension assembly components to access the old beehive spring. Position the new beehive spring in the tension assembly with the wider end at the base and the narrower end toward the tension nut. Reassemble the tension components in the correct order, ensuring the spring is properly seated and compressed by the tension nut.\u003c\/p\u003e","brand":"PD Sixty","offers":[{"title":"Default Title","offer_id":7690679582750,"sku":"125314","price":3.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0767\/4681\/files\/IMG_6008-Photoroom.jpg?v=1759439223","url":"https:\/\/www.vintagesingerparts.com\/en-au\/products\/upper-tension-beehive-spring-for-singer-vintage-slant-needle-part-125314","provider":"Central Michigan Sewing Supplies","version":"1.0","type":"link"}
