Make your robot or CNC move on rails super fast with a linear bearing platform. The platform is 34mm x 30mm and has four holes tapped for M4 machine screws so you can attach pretty much anything you want. All you need to get started is two 8mm supports and a precision-ground 8mm rod. Often times, CNC projects will have two of these on opposite sides to support a larger platform.
Comes as a single bearing. Adafruit have a bunch of bearings, supports and platforms that you may want to use with an 8mm based rail system so check out Adafruit's CNC category
