{"product_id":"bernina-bobbin-case-15347200","title":"BERNINA Old Style Bobbin Case, #0015347200","description":"\u003cp\u003eThe bobbin case is one of the most precision-sensitive components in your sewing machine. It cradles the bobbin in the lower mechanism, maintains correct lower-thread tension, and ensures the hook picks up the thread loop cleanly on every stitch cycle. When a bobbin case wears, develops burrs, or loses its spring tension, the result is immediate: looping on the fabric underside, skipped stitches, or erratic tension that no upper-thread adjustment can fix. Swapping in a fresh, properly tensioned case restores crisp, balanced stitches across all fabric weights. This part is also sold under alternate part number 0015347000.\u003c\/p\u003e\u003cp\u003eCompatible with BERNINA machines spanning several classic mechanical generations: the 100-170 series vintage line, the 500-series, the 700-series, the 800-series, the 900-series, and the 1000-1530 generation, plus the Aurora 430 and 440 families -- approximately 41 BERNINA models in total. Consult your owner's manual to confirm the correct bobbin case style for your specific model.\u003c\/p\u003e","brand":"BERNINA","offers":[{"title":"Default Title","offer_id":42215140524120,"sku":"0015347200","price":16.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/4092\/8600\/files\/v_hero_0015347200.jpg?v=1782356266","url":"https:\/\/sewlume.com\/products\/bernina-bobbin-case-15347200","provider":"Sewlume","version":"1.0","type":"link"}
