Need help with identifying and knowing the difference of ball screw nut, I being a Noob took the nut out of the ball screw, all bearing ball fell out, I managed to get them back in and it seems to work fine. I'm not too happy with it and ordered a new sfu1610-3 nut, I didn't realize that there are also sfu1610-2 nuts for sale.

So my question is does it matter, will the 3 circuit nut work on a 2 circuit ball screw? Now I don't know if what I have is 2 or 3 circuit, how can I identify them?

I want to know before trying it on, maybe return the sfu1610-3 and get a sfu1610-2.

Any help would be great, thanks
