Needle systems?

[Moti]

so I bought it and it doesn't fit, maybe I don't know where it the system writes

How does it not fit?  Needle system numbering is very confusing.  Do you have a needle that does work?  There is a very good chart that shows the dimensions for the different needle systems at this site that I found very helpful:

The needle system is only one part of the equation the other part is the size of the needle and the machines manufacturer determined the max size of needle for that machines needle system for that machine.

i) Depending on age of your machine and sub class you are also limited to a 130 (#21) needle which is good for V92 ( 30 ) thread. The needle you have shown is a larger 140 (#22) needle. Check your manual to see what is the max size of needle will fit your machine.

ii) Your machine was converted at some point to a 135 needle system.

On the top line at the right where it says "Nm 140/22" tells what size of needle. The 140 is the metric size and 22 is the US (Singer ) size of the needle. The larger the size number the stronger the needle is, has a larger eye to allow for larger threads.

Ok, I'm asking if what I marked in black is a needle system?

Maybe the needle I had before was wrong, but I don't know because that's how I got the machine

Yes that is the needle system of those Gross-Beckert needles.

If you still have the needle the machine came with. Is that needle longer, same or shorter then the new needles?

If system 134-35 is correct for your machine (according to the specifications), and you have inserted the needle all the way up in its mounting hole, and the rib faces due left, and the scarf faces due right, and it is threaded properly and won't pick up the bobbin thread, the machine is either out of time, or the needle bar has been pushed up due to a hard impact and the needle is now too short.

If it was pushed up, the needle bar can be lowered back to the specs so the eye of the needle is at the right height as the hook passes over it on the upstroke. If the needle bar is at the correct factory position, the hook may be retarded due to a thread jam. Clear out any loose thread, oil the hook, then retime according to the manual. The hook must intersect the needle in the scarf area, above the eye, on the upstroke when a loop has formed on the right side of the needle.

Yes I know, so basically I can line the machine with any needle I want?

As long as it is of the correct needle system for that machine (with a few exceptions) and the size of the needle is within the limits of what was specified for that model of machine.

If the needle that came with the machine is shorter then the new ones chances are that someone converted the machine to 135 X 16 needle system.
