What is the UY 128 GAS Needle?

2015_December-Needle-Differences-2

We recently added a new needle system for our Sailrite Professional Sewing Machine Series. The UY 128 GAS is a needle system that features an extra long scarf. Let’s take a closer look at what this means and how it can improve your sewing.

UY 128 GAS is the needle system for this new set of needles. The needle system refers to which needles fit in which sewing machines. The needle system is determined by the diameter of the needle’s shank and the needle’s length from the very top of the needle to the top of the eye. On the UY 128 GAS needles, as with most needles for industrial sewing machines, the shank is completely round. In this case, what sets the UY 128 GAS needles apart from other systems is their long scarf.

The scarf is the indentation above the needle’s eye that allows the thread to be grabbed by the shuttle hook under the throat plate to create a stitch. Longer scarves can help to eliminate skipped stitches. The Professional Sewing Machines have a very wide zigzag stitch and this can be problematic with some smaller scarfed needles. The taller scarf increases the tolerance on the right side of the stitch for the hook to catch the thread loop properly. It also reduces possible interference between the needle’s body and the hook or thread when the stitch width is at it’s widest.

All of the UY 128 GAS needles stocked by Sailrite are general purpose, round point needles so they will work well for a wide variety of sewing projects.

We’re excited about the ease of use with these needles and the wide zigzag stitches the Professional machines will easily produce when these needles are used. Sailrite is now recommending the UY 128 GAS needles as the standard needle system for all Sailrite Professional Sewing Machines.

Try these needles out for yourself. See our full selection of sizes at Sailrite.com.

    I see that you are recommending these for the Professional machines. How about for the LSZ-1?

      Hi Beth,
      Good question! We don’t recommend this needle system for the Ultrafeed LSZ-1, because it doesn’t offer any benefit with the oscillating hook in the Ultrafeed, because the shuttle assembly moves in time with the needle bar. The UY 128 GAS is more helpful with a rotary hook sewing machine like the Sailrite Professional. I hope that makes sense! Here’s a post we did on the differences between rotary and oscillating hook sewing machines for a little more information: https://sailrite.wordpress.com/2015/11/17/rotary-vs-oscillating-hook-sewing-machines/

    • Nikki said:

      These needles will also fit the Juki LU56Z and the Juki LU561.

      • Joanne said:

        Is that Juki LU 562 or is there a Juki LU 56Z

      • Nikki said:

        Hi Joanne, Yes! Sorry for the typo. It’s for the Juki LU 562.
