This set includes two fully supported 1200 mm (47.24 in) guide rails and four ball-bearing slide blocks to reduce play, noise, and wear. High-carbon steel shafts with electroplated corrosion protection and aluminum supports help keep motion stable in humid workshops, while tight tolerances support repeatable positioning for cutting, grinding, and DIY machine upgrades.\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cul\u003e\n\u003cbr\u003e\u003cli\u003eIncludes 2× 1200 mm (47.24 in) supported rails plus 4× SBR25 bearing slide blocks for a complete linear guide setup\u003c\/li\u003e\n\u003cbr\u003e\u003cli\u003eDelivers quiet, low-friction travel with ball-bearing blocks for smoother motion and reduced wear\u003c\/li\u003e\n\u003cbr\u003e\u003cli\u003eResists rust with electroplated rails and high-hardness carbon steel shafts for demanding shop environments\u003c\/li\u003e\n\u003cbr\u003e\u003cli\u003eMaintains accuracy with 0.1–0.22 μm surface finish and consistent hole spacing for repeatable positioning\u003c\/li\u003e\n\u003cbr\u003e\u003cli\u003eFits DIY builds and replacement installs on cutting, grinding, milling, and drilling machines—no special tools required\u003c\/li\u003e\n\u003cbr\u003e\n\u003c\/ul\u003e\u003cbr\u003e\u003cbr\u003e\u003cp\u003eUpgrade your motion system with a supported-shaft linear guide rail set built for stability under load and consistent results across long strokes. The SBR25 format is widely used in CNC routers, engravers, 3D printer add-ons, sliders, and automation frames where smooth travel and reliable alignment matter. With corrosion-resistant surfaces and rigid support, this kit helps reduce binding and drift during operation.
