Aluminum Linear Bearing Group Buy?

Our CNC's are designed to be compatible with common off the shelf aluminum linear ball bearings blocks. The blocks run very smoothly, and are definitely the top of the line upgrade for the machine. We would like to put together a group buy for the bearings. They can be very expensive. Typical costs are $115+ each. I think if we got enough people together, we could get the price down to $90 each (2 are required for a machine). To make an even better deal, we would ship them for free in the US.

This group buy has been cancelled in favor of our new CNC Building Blocks system. Our linear bushings will be just as good as the aluminum bearing blocks.

Let me know if you are interested! The bearings would be ordered and shipped from Japan, and would be of the higest quality.

I'll take a set. I'm in Canada though. Can I at least get a break on shipping? :)

They are pretty lightweight.

Maybe $10 for shipping in Canada?

Count me in. Are any physical modifications required on the MDF parts?

Nope!

We actually included holes and threaded inserts already on the gantry. These things will bolt right on, and maintain all the spacing of the machine. We designed it that way! ;)

Please excuse my ignorance...

Does this replace a part on the machine or is it an additional part?

Either way, sounds like a great idea (the group buy!)

These replace the X-axis u-bolts and Oilite bushings.

Excellent! When would you be doing this and should I hold off on assembly until I get these or are they simple to replace after final assembly?
Thanks!

They would require dissassembling a few parts.

I don't think the group buy would be accomplished for a month or so.
