Linear Rails and Rods

OpenBuilds extruded aluminum v-slot and c-beam rails are the foundations that build the open source community. The 6063 aluminum profile has a special "V" shape in the groove that is made to provide precise linear movement.

Our quenched and tempered O1 steel shaft provides an amazingly hard rod that will not deflect like regular steel rods and provides a hard surface that is perfect for linear motion with LMXUU bearings.
