Description:1. These linear bearing blocks are manufactured from durable aluminum materials to ensure strength, durability, and smooth operation, and the precise design ensures reliable linear motion. 2. The linear motion rail shaft slide guide offers stable support and precise linear movement with the help of the SBR12UU linear bearing slide slider blocks. The anti-collision block stopper prevents over-travel or collisions, ensuring safe operation. The design minimizes friction, reduces wear and tear, and maintains accurate positioning.3. Install the linear motion rail shaft onto the appropriate structure or framework using the provided mounting holes, and then attach the SBR12UU linear bearing slide slider blocks to the moving parts of your CNC machine or 3D printer. Ensure that the slider blocks slide smoothly along the rail shaft, and adjust the position of the anti-collision block stopper as needed.4. This linear motion rail shaft slide guide system is suitable for CNC machines and 3D printers, providing precise and reliable linear motion control. It is great for various applications such as engraving, milling, cutting, and printing to ensure smooth and accurate movement in these machines.5. Please regularly inspect and maintain the linear motion system to ensure optimal performance.Specification: Material: Aluminum Color: Silver Tone Rail Guide Total Size: 250x30x37 mm/9.8x1.2x1.5 inch(L*W*H) Rail Guide Dia: 12mm/0.2 inch Rail Guide Hole Dia: 5.5mm/0.2 inch Bearing Block Size: 38x38x28 mm/ 1.5x1.5x1.1 inch(L*W*H) Bearing Block Screw Hole Dia: M5 Bearing Block Hole Distance: 26x29 mm/1x1.1 inch Rail Guide Hole Distance: 150x22 mm/ 5.9x0.9 inch Package Included: 1pcs x rail guide with block stopper, 2pcs x bearing block, 1pcs x wrench
