HGR Linear Rail Kit: Comes with 2 x 78.74 in (2000 mm) linear rails, 68 x end caps, and 4 x rail clamps. This set is compatible with milling machines, 3D printers, industrial machines, and cutting machines

Rust & Corrosion Protection: Crafted from high-hardness medium-carbon steel (HRC58–62) linear rail and alloy steel slide blocks with pre-drilled holes. Electroplated coating is at least 10 μm to resist rust and corrosion even in humid basements

Silent & Smooth Sliding: Built-in ball-bearing slide blocks deliver quiet, low-friction motion while gripping the shaft tightly for stable linear travel. Less noise, less wear, more precision—every time you move

High Precision, No Deviation: Feature a 0.1–0.22 μm surface finish and 0.1 mm/2000 mm straightness, paired with precise hole diameter and spacing, this linear slide rail set ensures easy installation and repeatable positioning, even over long travel distances

Installation Made Easy: No extra installation tools are required. Designed with simplicity in mind, this linear motion guide rail kit installs quickly. It is suitable for DIY assembly or rail replacements
