This is the rotary hook (hook assembly) under the bed that catches the needle thread loop and passes it around the bobbin case. In the official JUKI parts list it appears for DNU series machines.\u003c\/p\u003e\n\u003cp\u003eThe hook works together with the needle, the bobbin case and the bobbin to form the lockstitch. Its point must be sharp and correctly timed to the needle, and its race must be smooth so that the thread runs freely.\u003c\/p\u003e\n\u003ch3\u003eDetails\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eJUKI part number: \u003cstrong\u003eB1830241SA0\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003ePart name in the JUKI catalog: Hook Assembly\u003c\/li\u003e\n\u003cli\u003eType: Hook\u003c\/li\u003e\n\u003cli\u003eListed in 1 model group of the official JUKI parts list\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFits these JUKI machines\u003c\/h3\u003e\n\u003cp\u003ePart B1830241SA0 is used on: JUKI DNU-1541\/DNU-1541H\/DNU-1541S.\u003c\/p\u003e\n\u003cp\u003eThe list follows the official JUKI WebPartsList.
