I´m thinking on building a machine with supported rails from Motion control products http://www.motioncontrolproducts.co....products_id=93

But I was told that these should not be used in any other position than horizontaly
And I think I have seen several machines that have used rails like these in every axles.

So the question is, how does these work vertical, or on the side?

I have not heard of these not working except for horizontal position. Was there a reason? I know they have different load capacity base on the direction of the load with respect to the rail.

I would be interested in any information on the working positions for these.
