Linear Rail Guide Kit, HGR20, 2Pcs 1000 Mm (39.4 Inch) Linear Motion Rails And 4Pcs Bearing Slide Blocks, Anti Rust And High Precision Kit, For DIY, CNC Routers, Lathes, Mills, 3D Printers

HGR Linear Rail Kit: Comes with 2 x 39.37 in (1000 mm) linear rails, 34 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 0.05 mm/1000 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
