The needle bar connecting link is a part for the Newlong industrial DD5 that connects the needle bar to the driving link on a sewing machine. It is responsible for transmitting the motion of the driving link to the needle bar, which causes the needle to move up and down.
The needle bar connecting link is a critical part of the sewing machine, and if it is damaged or worn out, it can cause a variety of problems, such as:
- Skipped stitches
- Uneven stitching
- Needle breakage
If you are experiencing any of these problems, it is important to inspect the needle bar connecting link and replace it if necessary.
The needle bar connecting link is usually located on the back of the sewing machine, near the top. It is a small, cylindrical piece of metal with a hole in the middle. The needle bar fits through the hole, and the driving link is attached to the other side of the connecting link.
To replace the needle bar connecting link, you will need to loosen the screws that hold it in place. Once the screws are loose, you can remove the connecting link and replace it with a new one. Be sure to tighten the screws securely once you have replaced the connecting link.
If you are not comfortable replacing the needle bar connecting link yourself, you can take your sewing machine to a qualified technician for service.
