20mm Linear Rail Guide Kit, 2 x 2000mm Rails, 4 Blocks

Linear rail guide kit delivers long-travel, high-precision motion for CNC, 3D printer, mill, lathe, and DIY builds—helping reduce chatter and improve repeatability over 2000 mm. Built from high-hardness medium-carbon steel rails with electroplated corrosion protection, this set is designed for smooth, low-noise sliding and stable load handling. Pre-drilled holes and accurate spacing support faster alignment and easier installation on compatible machines.

• Includes 2 x 2000 mm (78.74 in) linear rails, 4 x bearing slide blocks, 68 x end caps, and 4 x rail clamps for complete builds


• Delivers smooth, low-friction travel with ball-bearing slide blocks for quieter motion and reduced wear during repeated cycles


• Resists rust with ≥10 μm electroplated coating, designed for humid workshops, basements, and industrial environments


• Maintains accuracy with 0.1 mm/2000 mm straightness and 0.1–0.22 μm surface finish for stable, repeatable positioning


• Handles heavy loads with up to 27.76 kN static (180 kg) and 17.75 kN dynamic (116 kg) capacity for demanding applications

When your project needs reliable linear motion across a long axis, this rail-and-block set supports cleaner cuts, tighter tolerances, and more consistent print or tool paths. The precision-ground finish and tight-running bearing blocks help minimize play, while the corrosion-resistant coating protects performance over time. Ideal for new builds or replacement rails on routers, mills, and automation frames. Grab yours today and upgrade your motion system with stable, repeatable travel.
