Gantry linear motion ID question

Hi folks, I've been searching around trying to identify this part that is affixed to the gantry span tube steel that the v rollers of the y ride. Closest thing I found was from Avid that affixes cold rolled square to t-slot extrusion. This one seems to have the steel v top and bottom already as part of the assembly. Can anyone identify and suggest a vendor source?

I found it from another build here - duh....need to pay closer attention

Nice find, I like that both bottom and top bearing surfaces are designed into 1 piece. Most I have seen are separate top and bottom and installation spacing is then critical along the entire length so you don't get tight or loose spots as the lifter moves along the Y axis.

I agree with Plasmanewbie - great find! I've never paid much attention to how the other tables do it. Plasmacam has a unique method with rollers and gear racks, while my Avid CNC tables use a rack and pinion drive with single line linear rails. How many hours do you have on your table that these parts are already needing replacement? Just curious.

Thanks,
David

It sounds like you are looking for a steel V-slot bracket. There are many vendors that offer these brackets, and they can usually be found on websites such as Amazon and eBay. If you are looking for a specific size or style, you may need to contact a local industrial supplier.

That is pretty much it. Linear rail options in general for X and Y. Building a 4x8 table. I am looking for a vendor in, or ships to the US, in the longest length possible - often limited to 6/7 feet due to UPS and economy. Also a vendor with the best "value" - quality and price. Some I have found to be REALLY expensive in my eyes for what it is. If anyone has good resources (I have reviewed the resources sticky), would love to speed this part up as it is the part that is holding me back currently.
