The kit bundles a 560mm HGW20 square rail and two HGW20CA flange carriage blocks, delivering a rigid, low-friction slide that resists bending and deformation. Installation is straightforward and the four-point contact design means the rail handles loads evenly in all directions, making this a practical upgrade for machines where repeatable linear accuracy matters.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete kit:\u003c\/strong\u003e Includes a 560mm HGW20 square rail and two HGW20CA flange carriage blocks so users receive a ready-to-fit set for many CNC and DIY applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardened steel rail:\u003c\/strong\u003e The guide rail is made from high-carbon steel with quenching and tempering, improving wear resistance and long-term stability under load.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour-point contact design:\u003c\/strong\u003e The Goethe-style contact geometry distributes load evenly up, down, left and right and offers self-alignment to absorb minor mounting errors.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickened flange blocks:\u003c\/strong\u003e The HGW20CA flange slider blocks use high-quality bearing steel and extra material thickness to increase durability and load capacity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmooth operation:\u003c\/strong\u003e More steel balls in the carriage reduce friction for light, flexible movement and a longer service life when properly lubricated.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCustom length support:\u003c\/strong\u003e Factory direct supply and the option to request custom total lengths or spliced rails for runs longer than 2950mm.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe kit is ideal for small to medium CNC routers, laser engraving tables, gantry fixtures and DIY automation projects where a compact 20mm rail delivers stiff, accurate motion without complex mounting.
