The assembly works as a matched set: the rotary hook captures the needle thread and forms each stitch, while the included bobbin case (#0040777000) holds the bobbin and maintains correct lower-thread tension. Replacing both components together eliminates the guesswork of chasing tension problems caused by a worn hook surface or a fatigued bobbin-case spring -- you get a fresh, factory-toleranced pair that works in concert from the first stitch.\u003c\/p\u003e\u003cp\u003eThis hook and bobbin case assembly is designed for the BERNINA rotary-hook platform spanning the 100 through 900 generations, covering the 117\/217\/317\/517 compact series, the 540\/640 midrange models, the 740\/840\/940 computerized range, and the 750\/850\/950 quilting editions -- approximately 24 models in the BERNINA lineup. Compatible with BERNINA machines only.\u003c\/p\u003e","brand":"Bernina","offers":[{"title":"Default Title","offer_id":42181890703448,"sku":"0040787000","price":699.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/4092\/8600\/files\/0040787000-bernina-hook-assembly-bobbin-case-set-shopify-1.jpg?v=1781833293","url":"https:\/\/sewlume.com\/products\/old-style-bernina-hook-bobbin-case-set-0040787000","provider":"Sewlume","version":"1.0","type":"link"}
