Description:1. The linear guide rail and the carriage block are made from bearing steel material, and the mini linear guide is made of plastic material, to ensure stability and smooth operation.2. The linear guide rail has a limit block 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; Plastic mini linear guide to assist installation, do not let the ball fall off, suitable for MGN12H slide block.3. First, install the mini linear guide on the slider, 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: Linear Guide Rail: Bearing Steel Carriage Block Material: Stainless Steel Mini Linear Guide Material: Plastic Color: Black Linear Guide Rail Size: 300x12x8 mm/11.8x0.5x0.3 inch(L*W*H) Carriage Block Size: 45.5x27x10 mm/1.8x1.1x0.4 inch(L*W*H) Mini Linear Guide Size: 55x12x8 mm/2.2x0.5x0.3 inch(L*W*H) Package Included:1pcs x Linear Guide Rail, 1pcs x Carriage Block,1pcs x Mini Linear Guide
