Looking for linear bearing solutions

It sounds like your team is using aluminum extrusion. This is available from a number of manufacturers -- Item, Bosch, 80/20, etc. -- and each has a corresponding part that'll do what you're seeking. Start looking online or through catalogs for linear slides or linear bearings and that ought to be a good start.
