Its surface is treated with a polished hard chrome plating, which enhances corrosion resistance, reduces friction, makes the movement smoother, and ensures durability. Smooth Linear Motion: The shaft is precision-ground, ensuring excellent straightness, high accuracy, and minimal wobble. The aluminum alloy bracket is tightly integrated with the guide rail, effectively stabilizing the original guide rail. The ball bearings provide smooth, quiet, low-friction sliding. Easy Installation: First, use the included wrench to secure the two support blocks to the machine frame through the pre-drilled holes. Then, slip the linear ball bearings and shock-absorbing end caps onto the solid chrome shaft. Finally, secure the shaft to the support blocks. Versatile Applications: Suitable for upgrading or building various machinery and projects that require precise linear movement. Commonly used in 3D printers, CNC routers, laser engravers, small milling machines, sliding doors, automated drawers, camera sliders, and other hobbyist or professional fabrication applications. ## Features - Package & Size: This linear motion kit includes 1 pc 8mm x 250mm solid shaft, 2 pcs SC8UU linear ball bearings, 2 pcs SK8 shaft support blocks, 2 pcs yellow shock-absorbing end caps, and 1 pc black M4 hex key wrench. - Durable Material: The guide rod is made of 1045 steel, which is high in strength and rigidity.
