Specification Brand : uxcell BulletPoint : Easy Installation and Replacement - With standard and a well-machined design, this linear rail shaft can be easily installed or replaced, making it convenient for both professionals and DIY enthusiasts.Description: Durable Carbon Steel Linear Shaft - Made from high-grade carbon steel, this optical axis rod offers excellent strength and wear resistance, making it suitable for heavy-duty applications and ensuring a lifespan. BulletPoint1 : Package Included - 1pcs x MGN9H Linear Rail; 1pcs x Slider Block; Rail Length: 400mm/15.74"; Rail Width: 9mm/0.35"; Rail Height: 6.5mm/0.25" Block Length: 40mm/1.57"; Block Width: 20mm/0.8"; Block Height: 10mm/0.4" BulletPoint2 : Quality Material - The linear Rail Guide is made of bearing steel, surface chrome plating treatment, high toughness, high precision, rust resistance, smooth running, and low noise. BulletPoint3 : Smooth and Quiet - The rails are very smooth. The carriage moves smoothly and quiet, no binding, good quality, nice workmanship. Designed to achieve high-precision linear motion, with a low friction coefficient. BulletPoint4 : Easy To Install - Apply lubricant to the rail and slider again before installation. Help reduce friction and ensure smooth operation of the sliding mechanism. Not to remove the block unless it is necessary during the installation.Not to switch the blocks of the rail arbitrarily when installing the rail. To maintain the efficiency and longevity of the rail system, the rail should be regularly lubrication. Lubrication helps prevent burns and minimize wear. BulletPoint5 : Wide Application - The linear guide rail is widely used in automatic equipment, such as DIY CNC routers, lathes, CR10 series 3D printers, machine tools, laser welding machines, etc.Also applicable for large-scale transmission equipment, including industrial robots, and cracker machines.
