10 pk. Class "M" Bobbins (18034), (1143SU) for Long-arm & Industrial Machines

I've ordered these twice now for my Sailrite Fabricator industrial double walking foot machine. It has a separate bobbin winder on the side which I LOVE! I have found these bobbins to be very slightly inconsistent in the size of the hole in the center. Some fit the post of the bobbin winder so tightly that it's a struggle to get them on and off, and some are so loose that the post just spins inside without turning the bobbin. I'd say about 40% of the ones I've gotten had some kind of problem, but all but one time, I've been able to work with them and make them work. One out of the 15 or so I've used was just way too loose to work with. I'm only taking one star for the imperfections because they usually only cause minor inconvenience and even loosing one, they are still a good value. Obviously I would buy them again, since I have already done so.BTW I've also tried a less expensive set of bobbins available on Amazon and found every one of them to be far too large in the center. If the post on your machine has a self-adjusting spacer thing to accommodate very large center holes, this won't be a problem. Mine just couldn't get the larger ones on tight enough. While they're actually in the bobbin housing sewing, the inconsistencies don't matter at all.

These are nice quality metal bobbins that fit perfectly in my commercial long arm quilting machine.

Fits the Gammill Statler bobbin case!

Exactly what I was looking for.. recieved quickly..

Inconsistent sizing of the collar prevented me from being able to use any of the 10 bobbins on a Gammill. Several were too small and would not fit on the bobbin refill spindle. The others just slid around on the spindle and would not wind.

Items arrived as described.

My wife was concerned that the low price would result in an inferior product, but in this case they fit and work just fine

Good quality product but sadly they don't work on my gammill bobbin winder.
