20mm Linear Rail Kit, 2 x 1700mm Rails, 4 Blocks

Linear guide rail kit delivers smooth, accurate motion control for CNC routers and DIY X/Y/Z axis builds, helping reduce binding and vibration under load. This complete set pairs long HSR20 rails with matching bearing blocks for consistent travel and repeatable positioning. Built for workshop and factory automation setups, it’s a practical upgrade for lathes, mills, XY tables, and other machines where stable linear motion and low-friction sliding matter.

• Includes 2× 1700 mm HSR20 linear rails, 4× HSR20 bearing blocks, and dust-proof plugs for a complete motion slide setup


• Delivers smooth, precise linear travel with low friction to support accurate routing, milling, and positioning


• Supports heavy-duty use with 55C steel rails plus bearing blocks made from GCr15 steel and PA66 components


• Simplifies installation with pre-drilled mounting holes for fast alignment on CNC frames and machine tables


• Fits CNC routers, grinding machines, printing/paper equipment, automation rigs, and X-Y tables needing stable linear motion

When your project depends on straight, consistent movement, a matched rail-and-block system makes the difference in cut quality and repeatability. This linear motion slide rail set is designed for long travel applications where rigidity and dependable sliding action are essential, while keeping integration straightforward for custom builds and retrofits. Add it to your CNC or automation setup and get motion you can tune and trust—grab yours today.
