Hard to find bearing size.

[mamba max1]

I'm looking for a bearing that measures 8x17x6mm. (17mm diameter, 8mm hole, 6mm thick) I can't seem to find one anywhere. I've looked at ebay, avid, bocca, and acer. I need four for a project on my e-revo.


Any suggestions?

Edit, I was able to find my desired size on google, but they are $25 a pop............
