There's been alot of discussion in the Singer Quantum Stylist 9960 Facebook Group lately about the proper size bobbins for the Singer Quantum Stylist 9960 sewing machine. We had an ongoing post about this topic when I originally formed the group over a year ago. Well, it seems that there's still some confusion unfortunately. I will do my best to show the bobbins that came with my machine and the bobbins that I purchased for my machine. Yes....these are the same bobbins I use in my machine just in case you were wondering.
When I started to do research into purchasing the Singer 9960 over 4 years ago, I read every piece of information I could get my hands on. There were some discrepancies in the actual information and that was alarming to me. One source stated the correct bobbin size was 15J and another stated the correct bobbin size was Class 15....We have had members call Singer and inquire with this question only to add more confusion to this issue.
My Singer 9960 came with these 4 bobbins. I have never had an issue with using these bobbins. My machine has run flawlessly for more than 4 years. These bobbins are Singer Class 15J.
I purchased this package of genuine Singer Class 15J bobbins shortly after receiving my machine so I would be fully stocked with bobbins for all my projects. These bobbins are the same as the 4 bobbins that came with my machine only they are a slightly different color.
Here's a picture of the 2 bobbins side by side. The one on the left is one of the Class 15J bobbin's that came with my machine. The one on the right is from the package of Singer Class 15J bobbins I purchased. They look pretty flat to me and are the same in size and shape. They appear to have a slightly purple coloration to them. I don't have any Class 15 bobbins on hand, so unfortunately I can't show them side by side.
Here's a picture of the Class 15J bobbin inserted into the Singer 9960 properly. Notice how it fills the bobbin casing area completely. There's no extra room around the bobbin and it fits snugly.
Hope this explanation helps if you too were wondering about the correct bobbin size for the Singer Quantum Stylist 9960.
Have a Happy Creative Day!!
