AMK horizontal grinder small wheel size

[Happychicken]

Hi all I am trying to do a serrated knife but I need to change my small wheel on my AMK horizontal grinder. Current size is a 3/4 I need a 3/8 or a half inch wheel. I purchased some small wheels but the bearings don’t fit the small wheel holder. I guess there are different sizes?
Does anyone know what wheels will fit this? Thanks

Did you contact AMK and ask for a recommendation or the bearing size?

You could measure the current bearings and check against some of te ones online to see if you get a match. Post the size of them and someone here might check theirs and see it they are the same.

I will measure the bearing!! I will post the size! I have not reached out to AMK yet
I thought there might be two standard sizes and I just picked the wrong one

The wheel is 3.5 inches long the bearings are 1 1/8 but have a 1 1/4 lip around them

Standard small wheels are 3.15 inches long with 7/8 OD bearings so I’m guessing AMK made their own. You will probably have to get one from them or have Sunray make you one.

Yes that’s the same size I bought. I will research Sun ray and talk to AMK tomorrow thanks for everyone’s help with this.
Bye the way it looks like brodbeck ironworks uses the same size wheels but they don't offer them under 3/4 of an inch.

Yes AMK makes their own and the smallest they offer is 1/2"
