Magnetic Core Prewound Sideless Bobbins keep the bobbin thread from backlashing in the bobbin case, which causes thread nesting on the bottom side of embroidered fabrics.*

  • Please remove any circular perforated backlash metal disc spring from inside your bobbin case when using Magna Core bobbins, so they have better contact with your metal bobbin case.(Remove perforated flat backlash spring from inside metal rotary bobbin cases when using magnetic bobbins to stop the bobbin from turning after machine stops. Magnetic core bobbins need better contact with bobbin case.)

  • Fil-Tec's revolutionary magnetic core embroidery bobbin is the only bobbin specifically designed to sew without tension variation throughout the entire bobbin. The magnetic core, combined with our advanced EB "crosslink" technology optimizes dynamic thread delivery to create consistent tension from beginning to end of each bobbin.

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

  • Fewer Bobbin Changes
    Our 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 bobbin

The following is some of the feedback we have received from Fil Tec customers and users of Fil-Tec Magna Glide Bobbins… C.H. Holderby Washington “With Magna-Glide M bobbins we were able to increase our customer’s SPM from 630 to almost 900. Needless to say, we were pleasantly surprised. The thread runs cleaner, and appears much stronger”. Atlantic Coast Embroidery New York “With Magna-Glide I am able to get 20% more stitches per bobbin. At first we did not believe our own test data. Magna-Glide has a more “even-flow”, and is not as jerky as other prewound bobbins.” JHD Distributors (ZSK) Texas “We ran Magna-Glide on ZSK and Aemco machines, and they performed very well, there is no doubt that we are getting a better yield with Magna-Glide. We also love the flat-laying, even-tension we get with your new bobbin.” Twin Peaks Embroidery Washington “My hat goes off to you. Your M bobbin runs much cleaner, and pulls nicely. It seems stronger, and we enjoy the 33% more stitches per bobbin that we get from Magna-Glide.” S.A. Smith United Kingdom “ Our 8 head machine averaged 2.4 million stitches per day over 3 days running at over 1,000 spm (10am-5pm) without a single bobbin thread break and only 14 top thread breaks (and not a single reject badge). The design had approx. 144,000 stitches and the machine completed the design using only 2 bobbins per head.” “One of our single head machines averaged 490,000 stitches per day running at 1,200 spm and once again without a single thread break and only 6 top thread breaks the whole show. This was a good example for the Magna-Glide as it was mainly step stitch fill which uses more bobbin thread. I have been in the in the industry for over 28 years and I have never come across a bobbin (either wound or pre-wound) that even comes close to the performance of Magna-Glide.” Sew Busy Custom Embroidery Georgia “I must say that I was skeptical about the hype of Magna-Glide until I saw that the bobbins do in fact run all the way out without a change in the bobbin tension. I have also not experienced the lint buildup under my spring like I am used to seeing with my other bobbin. My hats off to you for coming out with such a unique item! I don’t see myself ever reverting back to the old sided-bobbin.”
I have a Brother Nouvelle 1500S. Can I use the magna glide bobbins in this machine. Because of the magnetic band in it I was concerned.
I use these in my longarm quilting machine.

Magna Glide bobbins work better in embroidery and quilting machines because of the frequency of high speed start and stop, and to prevent backlash of bobbin thread. But since they are sideless, Brother recommends only metal bobbins for their PQ1500S. Magna Glide bobbins may work, but Brother did not develop the bobbin case for anything but metal bobbins. As a matter of fact, the Brother bobbin case already has an anti backlash insert in the bottom of their bobbin cases to prevent bobbin thread from spinning off after abrupt stops. So it would have to be removed before trying sideless bobbins.
