What is the bearing size for FK10 ballscrew supports?

[ttodorov]

Hello all,

I am trying to find the bearing sizes for FK10 and FF10 ballscrew supports. You can buy those on the cheap from Chinese manufactures, but they come with radial bearings. I want to replace the FK10 bearing with angular contact one, but am unable to find the size. All I know is the ID is 10 mm. So if anyone has this info, please post it.

I am aware that some sellers on Aliexpress and Ebay are offering a version of the ballscrew supports with angular contact bearings pre-installed. However, as I have had bad experience there, I would like to source and replace the bearings myself - just need the correct size/type.

And lastly, I know I can find a lot better quality supports from brand name manufacturers on sites like Misumi or McMaster, but I can't afford those...

Thanks!

Hi,
I found this in a THK publication. It suggests 7000 bearings, 10 x 26 x 8.
