304 Stainless Steel Rod Diameter 4mm-18mm Linear Shaft Metric Round Rod Ground Rod 100/200/300/400/500mm/600mm/700mm/800mm Long
Aliexpress UK
Description:Durable Material: The guide rod is made of 1045 steel, which is high in strength and rigidity. 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.
