Hey Ray,

If you want to go cheap:
http://www.bearing-fastener.com/Ball...pport-210.html

Think linearmotion2008 gets all the stuff here, same for worldofcnc, think 25 dollar a piece max.

otherwise misume for a normal price, the rest is expensive.....!!!

regards,

Roy

Ray,
I am using them on my IH conversion. They can be preloaded quite easily and seem to be working well. Here is a good link on a way to set the preload when using non-matching AC bearings.

Edit: I have only used the singles.

Has anyone here used AC bearings from VXB? They're certainly cheap, but how good are they? Are the double-row ones pre-loaded adequately for use as a ballscrew support? Are the singles made precisely enough to be duplexed with appropriate preload? How much are 7202s/6202s from NSK or another reputable manufacturer?

Devin,

That link doesn't work.

I ordered a pair of singles, and a double, and they actually seem pretty good. The singles, when tightened together, get pre-loaded to what seems a reasonable amount - some drag, but not a lot. The doubles also seem to be backlash-free.

Ray, I fixed the link.

Ray, I fixed the link.

Nope, still broken. The target of the link is identical to the displayed text, right down to the "...". Maybe try using tinyurl.com.
