C-Beam Linear Rail is the ultimate solution combining both linear motion and a modular, structural framing system. It's lightweight yet rigid and provides an ultra smooth track for precise motion.C-Beam is a profile based on the popular V-Slot linear guide system. It incorporates a C shape profile which gives added strength and functionality. It incorporates the excellent original V-Slot system. Because of the V-Slot system every side of extrusion can be used as a linear guide. Because C-Beam works hand in hand with V-Slot, all standard V-Slot gantry plates, wheels, mounts, brackets and fasteners are compatible with this extrusion.
