Baby Lock Metal Bobbins, L Style, Rotary for Group G, #55623S

This 10-pack of metal L-style bobbins keeps your rotary-hook machine stocked and your sewing uninterrupted. Constructed from steel, these deep-groove bobbins wind thread evenly and seat securely in the bobbin case, delivering smooth, consistent lower-thread tension whether you are running light home-sewing projects or pushing a semi-industrial quilting or embroidery machine through heavy production. Having a full set on hand means you can pre-wind multiple thread colors and swap them in seconds rather than stopping mid-seam to rewind a single bobbin. The metal construction holds up to repeated winding cycles without deforming the groove walls, maintaining the reliable thread path that L-style rotary systems depend on.

These bobbins are built for the L-style (rotary) bobbin class used across a wide range of brands and machine families. Confirmed fits include Baby Lock BL/BMP/BMY/BNAL/BNT/EMP series, Brother PR and PQ quilting and embroidery lines, Bernina 1000-series and Bernette 300/400-series, Juki DDL industrial and TL quilting models, Janome 1600P high-speed series, Singer 20U industrial and 306-series, Pfaff 1200 Hobby Grand Quilter, Husqvarna Viking 2780/2840 and Mega Quilter 1200, plus Riccar, Consew, and Elna models using the L-style platform. Also sold under part numbers SA159 and H12413002.
