SBR25 Linear Rail Kit, 2 x 1200 mm Rails, 4 Blocks

SBR25 linear rail kit delivers smooth, precise linear motion over long travel for CNC, milling, drilling, and automation builds. 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.

• Includes 2× 1200 mm (47.24 in) supported rails plus 4× SBR25 bearing slide blocks for a complete linear guide setup


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


• Resists rust with electroplated rails and high-hardness carbon steel shafts for demanding shop environments


• Maintains accuracy with 0.1–0.22 μm surface finish and consistent hole spacing for repeatable positioning


• Fits DIY builds and replacement installs on cutting, grinding, milling, and drilling machines—no special tools required

Upgrade 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. Grab yours today and get your build moving with cleaner, quieter linear travel.
