Product Details

MakerSlide is an aluminum extrusion with two special V-shaped rails for wheels to roll on.

This component is interesting for people designing CNC machines because it acts as both the structural support and the linear bearing system. The biggest design, cost and fabrication hurdles in a new CNC machine design are the linear bearings. There are a lot of commercial and DIY solutions out there, but none support an easy, low cost and rapid fabrication philosophy.

The basic bearing concept is not new. The inventor of the MakerSlide, Bart Dring, had used it for years in his own designs and many high end commercial systems use it. This system is traditionally called a V wheel running on V rail. The problem with the commercial systems is that they are expensive, require a lot of accurate fabrication to integrate, and don’t seamlessly integrate into standard extrusion systems. The MakerSlide solves all three of these issues.

MakerSlide is a V rail integrated into a standard extrusion profile. If you are working on a CNC system like a 3D printer, CNC Mill, or CNC Router this MakerSlide might be the right structural support and linear motion system for you. We use it in the Shapeoko CNC Mill.
