Description:1. The linear guide rail and the carriage block are made from bearing steel material, which is wear-resistant, heat-resistant, and has good dimensional stability to ensure stability and smooth operation.2. The linear guide rail has plastic limit blocks at both ends, which can play the role of collision protection; The MGN12H sliding carriage block can provide precise linear motion control for 3D printers and CNC machine tools, minimizing vibration, ensuring smooth motion, and reducing equipment wear.3. First, place the slider parallel to the guide rail, and then gently push the slider into the guide rail. After the slide into the guide rail, the installation is successful without dropping the steel ball.4. This linear guide rail system is great for 3D printers and CNC machines, providing accurate and reliable linear motion, and is also suitable for various applications, including precision printing, engraving, milling, and other tasks requiring controlled movement.Specification: Material: Bearing Steel and Plastic Color: Red Green Linear Guide Rail Size: 200x12x8 mm/7.9x0.5x0.3 inch(L*W*H) Carriage Block Size: 46x27x10 mm/1.8x1.1x0.4 inch(L*W*H) Package Included:1pcs x linear guide rail, 2pcs x carriage block
