How to Choose Bearings for a Custom Rack and Pinion Setup?

[Makaram]

Hey,
I'm wanting to create a custom Rack and pinion set up where force is applied to the rack, turning the pinions.
In order to do this what would be my best method of bearing? Can this be integrated into the design of the Rack itself?
Also if the rack were to be curved what would be the best method in this scenario?

Thanks
Matt

Many different types of linear bearings could be applied to the rack. Thompson rails, Del-Tron -type bearings, many others. For curved, my first thought would be something like Bishop-Wisecarver products. Or more simply, mount the curved rack on a transverse axle shaft suspended in simple bearings.
