When comparing Home Machine needles to Longarm needles, there is quite a difference in regards to the needle style, designation, point, scarf, groove, and shaft. It's difficult to draw an even comparison since all home Machines will accept flat-shanked needles (our Titanium-coated Topstitch needles, for example) and within the Longarm machine industry, there are many different styles of needles and brands vary on which style of needle their machine actually takes.
Why is this important? If an incorrect needle style is used on your machine, then your stitching won't be as correct and it could also affect your timing due to the incorrect length/scarf of the needle. But don't fret about this, we've made it very easy to find the right needle by breaking down our Longarm needles by machine brand.
We sell and use Groz-Beckert longarm needles for our longarm machines. We run them in many different machine brands and love the stitch quality of these needles. The style of needle we use and sell is of the 'MR' style. The designation of 'MR' is "Multi Range" (also known as SAN: Special Application Needle) which was created for the textile industry, more specifically, the 'MR' needle style was developed for automated sewing processes with multidirectional feeding systems. If your machine is not stationary (such as a Longarm machine), then the 'MR' needle style is the one to use. It has several key features which are superior to other needle styles such as:
With the naked eye, it is hard to tell a difference between needles. But when you are stitching at 500 or 1,500 stitches per minute, you can definitely tell when you have a good needle or a bad needle.
The 'MR' style needle is also available with a Titanium-coating for several Longarm machine brands (Brands which take the specific 134MR designation). This takes an excellent needle platform and adds a lot more value as titanium-coating keeps your point sharper, and extends the life of your needle by at least 6 times.
