Does anyone know what type of spindle motor pulley and belt type is used on the X3 mill? It seems to be some type of weird 6 mm pitch. I'm trying to replace the spindle motor with an AC servo and would like to get some compatible belts and pulleys from a place like Stock Drive Products.

thx

I believe GT2 has curvilinear teeth. The replacement belt that came with the X3 has trapezoidal teeth. It just has a weird 6mm pitch. Looks like I'll either modify a spare motor pulley from Grizzly or replace the pulleys\belts with something more standard.

You are correct sir! it does have curvilinear teeth, but I mis-read your post that is the belt for the SX3, suprises me that they would use something different on the X3.

I believe the curvilinear belts can handle more power. Maybe they switched to a different belt on the SX3 due to the bigger motor and direct drive.
