Hello all, There have been a couple of threads lately asking if one small wheel would fit a different manufacturer's small wheel holder. That got me to wondering, just what are the dimensions of small wheels? From my meager memory it seems KMG is somewhat the standard for small wheels? Is that true?

Does USAKnifemaker's small wheels fit the KMG holder?

Just what is the dimensions of various small wheels? Distance from end to end? I made a set of small wheels using R6-2RS bearing which are 3/8" ID and 7/8" OD, with 3-1/4" outside to outside measurements. Not sure where I came up with those, but was thinking somebody gave them to me as KMG dimensions.

It would be good to have a list of different manufacturers small wheel dimensions listed in a sticky for folks who wish to build their own small wheels and holder. It's so easy to build.

I was thinking USAknifemaker was compatible with KMG but missed that when getting the bearing info. I wonder if most manufacturer folks use KMG dimensions?
 
I have three different small wheel arms/sets and all are different. There are probably half a dozen (or more) arrangements of bearings and ways they mount.
 
Hey Ken 3 1/4" wide would not fit in my holder.
Mine are -
bearings 7/8 od x 3/8 id x .280 wide
Overall width is 3.160
I have a 3/4 diameter wheel

Its been a while but I am 95% sure mine came from USA Knifemakers
