SBR20 Linear Rail Kit, 2000mm Rails, 4 Slide Blocks

SBR20 linear rail kit delivers stable, smooth linear motion over long travel, helping your CNC or workshop machine cut, drill, mill, or grind with better repeatability. This complete set includes fully supported 2000 mm rails and ball-bearing slide blocks engineered for low-friction movement and consistent positioning. Corrosion-resistant plating and hardened steel shafts support demanding loads, while precise hole spacing simplifies alignment during installs or upgrades.

• Includes 2 x 2000 mm (78.74 in) supported rails and 4 ball-bearing slide blocks for a complete linear motion guide setup.


• Delivers quiet, low-friction travel with tight shaft grip to reduce vibration, noise, and uneven movement.


• Resists rust with electroplated rails (over 10 μm) plus aluminum supports—built for humid shops and basements.


• Supports heavy loads for machine builds and replacements; designed for stable travel under dynamic and static forces.


• Fits cutting, grinding, milling, and drilling machines; installs quickly with precise hole spacing and alignment-friendly design.

Built for makers, maintenance teams, and DIY machine builders, this supported linear rail set helps keep motion straight and predictable across long distances. Hardened steel shafts and smooth-running bearing blocks reduce wear on your system and make fine adjustments easier during setup. Whether you’re upgrading an existing axis or assembling a new CNC frame, you’ll get reliable linear travel with less tuning time. Grab yours today and get your motion system running smoother.
