Help me identify this belt?

[radfordc]

I bought a belt drive for my mini-mill several years ago and this is the belt that it uses. The belt is clearly marked "Gates 110". However, the only belt that I can find in the Gates catalog is the TruFlex 0110 that is described as being 1/4" x 1/8" with a circumference of 11". My belt is 11" circ., but is much narrower. Mine is less than 1/8" wide and about 3/32" thick.

Any idea of what this is and where to get a new one?

Try asking gates for the specifications of a 280-2MGT03
which is a sync belt -


see if that's the same as your belt

I cant tell if its a syncronising belt or just a segmented V belt

What is the make and model number of your mill?

Cummins 7877 Mini Mill, but I bought an aftermarket belt drive on Ebay several years ago that uses this belt.


I think maybe the belt is a 3M300?

Hi Radford

a 3M300 would have a circumference of 12" do you have enough adjustment for that?


Peatoluser and I suggested the 3M280 because it has a circumference of 11" which is what you measured the old belt at.

I have the aftermarket belt drive from Little Machine Shop for my Cummins 7877 Mini Mill.

The belt drive looks like this:

Yours may not be the same, or it could be...

My earlier measurement wasn't accurate. After examining the old belt carefully I can see the code 3M300....I think.
