    Used for Knee Mill Retro

    Posted by Davis on 22nd Apr 2019

    So I pursued converting a medium sized Harbor Freight knee mill to ball-screws, and found myself needing a much smaller diameter bearing & assembly for the helical gears that raise & lower the knee.. enter Fast Eddy Bearings and the 6704-2rs... wow, these things are tiny(so to say), but they'll seem to do the task just fine. I've already made my mods and they are working great where I put em. Quick Shipping, and some good quality stuff. Thanks guys!

    Before ordering these bearings I priced them locally because I didn’t want to wait for the shipping. After looking around I couldn’t find them. So after looking on the internet Fast Eddy’s were the cheapest bearings I could find. With that being said I was expecting subpar bearings but to my suprise they surpassed my expectations. These bearings are super smooth and feel way better then most I’ve used. Thank you Fast Eddy for a great valued product!
