SBR20 Linear Guide Rail Set, 1000mm, 2 Rails 4 Blocks

SBR20 linear guide rail set boosts CNC and automation accuracy with smooth, low-friction travel and stable load handling. This 1000 mm (39.4 in) linear rails and bearings kit includes two supported guide rails and four SBR20UU bearing blocks, designed to reduce stutter and noise while maintaining repeatable motion. Built from high carbon steel with an aluminum base and a corrosion-resistant surface, it’s ready for router tables, laser engravers, 3D printers, and DIY machine builds.

Built for makers and maintenance teams who need dependable linear motion, this supported rail system helps keep sleds and gantries tracking true under load. The aluminum support base increases rigidity, while the bearing blocks maintain consistent movement across the full 1000 mm travel—ideal for CNC router machines, mills, lathes, engravers, and trainer rocker plate builds. If your project demands smoother motion, less binding, and cleaner positioning, upgrade your motion platform and grab yours today.
