Need help identifying the linear bearings please.

Hey guys, another question form the newbie

I was surfin ebay just looking at CNC stuff. I came across some linear bearings that has 6min left, and I won the bid for $11.50+$30.35 for shipping. $42 isn't bat for 6 linear bearings!

My problem, is that i got ahead of myself without checking the quality, the size, or the strength they can handle. I ordered the IKO linear bearings.

IKO LWH30C1BT2HS2 Linear bearing

ebay link: http://cgi.ebay.com/ws/eBayISAPI.dll...torefresh=true

I looked on IKO's website, but i couldin't find the size rod i will need to use these. Are all linear bearings use the same rod? do they vary? Are these bearings good? If anyone can point me in the right direction would be highly appreciated!

For the linear rails, does this sound right?

H=26mm
W=28mm

They are probably 30mm rails, based on LWH30. If you can find cheap rails, that's a really good deal you got. Try this.
