Searching for ultra low friction ball bearing with 5/16" bore

[hydrobro]

Does anyone know where I can find a relatively inexpensive ulta-low friction ball bearing with 5/16" bore. My application demands really low friction under 10 rpm, room temperature environment. i have tried a skateboard bearing called Bones, Swiss Ceramic @ $15.00 each. The bearing is ok but my competitors are using bearings that are even better. Any help on locating a possible source?

Use a self aligning ballbearing.
