Feature: 1. WIDE APPLICATION: This linear guide rail is suitable for most automation equipment, widely used in CNC parts, 3D printers, semiconductor manufacturing equipment, printed circuit boards and so on. 2. BEARING STEEL MATERIAL: Made of bearing steel, this linear slider rail has a low friction coefficient and no resistance when bearings are placed on the rail. 3. SMOOTHLY MOTION: The linear rail is corrosion prevention, and smoothly, making it ideal for most 3D printers, perfect for sliding block motion and translation. 4. LOW FRICTION: With the use of a linear guide rail slider, the friction of the machine is reduced, ensuring smoothly operation of the machine. 5. ENHANCED EFFICIENCY: By using this linear guide rail, the overall efficiency of the machine is improved, providing a faster and more stable linear motion solution.
