Versatile Applications — The MGN12H linear rail and linear bearing can be used in various applications such as CNC machines, 3D printers and other automatic devices, making it a versatile choice for different needs.
The sliding stone usually lacks 2 steel balls on each side, this is a normal process. When the slider is fully loaded with balls, it will clamp easily because the balls need some space on each side to work properly. However, we will supply you with additional steel balls in the package so you can add your own.
Non-bent, smooth surface — The excellent manufacturing technology and good packaging technology ensure the straightness and smooth surface of the linear guide completely.
EASY INSTALLATION — The KGTCN MGN12 linear rail is a steel support rail with pre-drilled holes, allowing you to set up your linear motion system quickly and effortlessly.
Anti-shedding — A rubber stopper on each side of the linear rail can prevent the sledge block from falling out.
Advantages — Made of high quality passivated bearing steel with low coefficient of friction, which provides no resistance when placing the bearings on the rail. Durable, corrosion resistant and smooth, perfectly fits most 3D printers and CNC parts.
