HGR Linear Rail Kit: Comes with two 23.62 in (600 mm) linear rails and a ball screw. This set is compatible with milling machines, 3D printers, industrial machines, and cutting machines

Premium Ball Screw: This linear guide rail kit features a wear-resistant ball screw, high-precision BK12/BF12 end supports, high-load coupler, and a corrosion-resistant nut housing. Maintains repeatability over time, even under daily use

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
