Data cut cnc router

[mdred68]

I started my build about three years ago. I haven't touched in two.I bought plans from data cut, i feel it is a real good design. I have just about all of the cast aluminum part done. I went to get a quote from a local bearing store and part number 2da-12-JOBL36 costs about $2500. Thats way more than i want to spend on the y axis. Is anyone out there building this machine? Haas anyone out there come up with a different way of completing this part of the build? Thank you in advance for all your help.

I'll bet that price made the old ticker miss a few beats.

Google found an RTF file on the www.data-cut.com site concerning the bearing but I can't connect to the site to look at it or go to the home page for some reason. What's so special about the bearing?

Wild guess is it's an entire unit --with the works...!

Judging by their numbering system....page 246 of this pdf
file...

Looks like maybe an out of date stock #....??

I'd guess you need to build it from scratch.

Here's a link to a build where someone went a different route to save some money on their build.

Well, I think that's what it looks like anyways....

Strange. This morning I can go to both links that I posted, in just a second or two.

That's certainly not the round ball bearing made of 100% pure flame hardened Unobtanium that I was thinking it had to be.

Those Thomson slides are what I've used on my modified Taig mill for years now. Great all-in-one units, but I got them for "cheap" on eBay and from someone on the forum. In fact I have (2) 42" 2DB-12 units sitting behind me right now. -> 32" travel when you subtract the 6" carriage + 4" of end caps/bearings for the ballscrew.. (2DB includes ball screw, nut, end plates / angular contact bearings + motor mounts. 2DA is just the linear bearings apparently.) If *just* the bearing part is $2,500, I can't IMAGINE what the 2DB cost new!!!

Funny, just the other day I was thinking of using the ballscrews from these units in another machine and selling the bearing (2DA) part of them... You could cut them to 36" if you're sticking to the exact plans.. Any interest?
