PLEASE NOTE:  If you own a home embroidery machine, these bobbins will work, however, we recommend an alternate product - the Clear Glide Pre-Wound Bobbins.

Magna-Glide Pre-Wound Embroidery Bobbins

Uniform Tension Control - The patented Magna-Glide magnetic core creates consistent delivery throughout the entire Magna-Glide bobbin. No more interruptions for tension adjustments as your bobbin gets smaller. Magnetic core prevents backlash or over spin and eliminates the need for check springs.

Fewer Bobbin Changes - The  Magna-Glide magnetic core bobbin offers significantly more stitches per bobbin reducing defects and increasing productivity.

Clean Running - Advanced EB cross-link technology reduces lint and residual build-up in the bobbin case and tension spring. The result is a more trouble-free Magna-Glide bobbin.

High Quality Yarn - Fil-Tec uses only the finest quality, high tenacity polyester yarns to make it patented Magna-Glide magnetic core embroidery bobbin.
 

Magna-Glide Tension & Install Diagram

Magna-Glide is a revolutionary improvement in embroidery bobbin technology designed to improve sewing quality, consistency and productivity. However, because of the unique core and yarn construction, the following are recommended during initial set-up:

• REMOVE ANTI-BACKLASH SPRING:
  Some embroiderers use anti-backlash or check springs inside the bobbin case when using conventional sided bobbins to stop any bobbin over-spin. This is not needed when running Magna-Glide bobbins as the magnetic bobbin core will prevent bobbin over-spin. In fact, anti-backlash or check springs placed in the bobbin case may damage the sideless bobbins
   
• LOAD BOBBIN SO THAT IT TURNS CLOCKWISE:
  The magnetic tip of the core must sit on the bottom of the bobbin case, as this is what will create the uniform draw-off tension from the beginning to the end of the bobbin.
   
• SET THE BOBBIN TENSION:
  Set the bobbin tension at 18-22 grams or do a drop test (bobbin case should drop about one inch when you hold the yarn and gently bounce the bobbin case up and down as if you had a yoyo in your hand).
