Bobbin Case for SINGER Industrial Straight Stitch Machine (Ref. 149063)

The bobbin case is the essential part where the bobbin is inserted, being the heart of the rotary hook system. In high-speed industrial machines, wear on this part or loss of spring tension results in serious sewing problems, such as broken threads, looping under the fabric, or unwanted slack at high speeds.

This replacement part solves these problems immediately. Designed to withstand the rigors of industrial sewing, it features a wide opening slot ("no back lash" system) to prevent the bobbin from unwinding too much thread when the machine stops suddenly. It is the classic reference for historical and modern SINGER industrial straight-stitch machines.

Important notice: Exclusive part for industrial sewing machines. Not compatible with household machines.
