This Linear Sliding Guideway consists of a 300mm steel rail and a carriage slide. The 9mm wide steel rail can be fixed to our MakerBeam slotted aluminum extrusion. The carriage slider is 30mm x 20mm and has four holes tapped for M3 machine screw.
CAUTION: Face the carriage slider downward when you remove it from the steel rail. This is to prevent the metal ball inside the carriage slider from falling off.
