need help with linear rail choice.

[HMD]

I am in the design mode of building a 5x10 plasma table which will have rack-n-pion and drive on each side.One quote was from Lintech,SA16-144-CR at $1,266 each and the double linear bearings are $221 each.Ok ,then I get a quote from Techno,Inc and the Isle series double rails model 300 was $348 each and the 300 carriages are $108 each.Would like to here from some of you if you have used any of these .I didnt see any tolerance on the Techno specs.Thanks,Brad.

Get Hiwins from www.automation4less.com .

For a plasma machine, the 15mm HG series will be more than sufficient.

Also try their surplus/overstock site: automation-overstock.com. I just bought 20mm Hiwin rails (3000mm)and trucks from them: Great price and great service.
Since I live pretty close I picked them up and has chance to look around in their warehouse: They have miles and miles of rails.

Good luck!

Guys,

Linear profile rails are just about the most expensive option out there for linear axis. I've used redi-rail from pacific bearing (www.pacific-bearing.com) and have found that I get just as nice of a system and usually save 25-50% from the profile rail.

However, if you're going to try and hold a tolerance of +/- 0.002" or better on your working piece, then you really need to go with a profile rail. Hiwin makes a nice rail and their quality has gotten a whole lot better over the years. I personally like to use NB's slide guides(http://www.nbcorporation.com/). The price is just a little bit more than Hiwin (not enough to make a difference) and the quality is probably 10x better.

Good luck

Jon

I paid $180.70 per rail and $29 per truck. But you can look up the prices directly at automation-overstock.com.

They do have a huge warehouse full of stuff. Very good prices and very good service!
