Linear Rail Guide Kit HGR20, 1000mm, 2 Rails 4 Blocks

HGR20 linear rail guide kit delivers smooth, low-noise linear motion with high positioning accuracy for CNC, 3D printer, and automation builds. This complete set combines long-travel 1000 mm rails with ball-bearing slide blocks to reduce friction and play, helping you cut cleaner, print more consistently, and upgrade DIY machines with stable, repeatable movement. Corrosion-resistant plating supports use in humid workshops and basements.

• Delivers quiet, smooth travel with ball-bearing slide blocks for low friction and reduced wear


• Supports precise motion with 0.05 mm/1000 mm straightness and fine surface finish for repeatable positioning


• Resists rust with electroplated coating (≥10 μm) for tougher shop and basement environments


• Fits common CNC routers, mills, lathes, 3D printers, and linear motion DIY assemblies


• Includes a complete kit for fast setup with pre-drilled rails and matching bearing blocks

When long travel length and stable guidance matter, this linear motion rail set helps keep movement controlled across the full stroke—ideal for upgrades, replacements, or new builds where accuracy and rigidity are priorities. The hardened rail material and tight-running blocks are designed to maintain consistent performance under load, while the included accessories streamline installation and alignment. Grab yours today and get your next CNC or 3D printer motion system running smoother and more reliably.
