Linear guide rail set SBR20 delivers rigid, smooth linear motion for CNC routers and DIY automation projects, helping you hold accuracy under load with less binding and chatter. This kit includes two 2200 mm supported rails and four SBR20UU bearing blocks for long-travel builds where alignment matters. High carbon steel shafts on an aluminum base with a corrosion-resistant surface support stable, repeatable movement for router, mill, lathe sleds, 3D printers, and laser engravers.

Built for builders who need reliable motion over 86.6 in/2200 mm travel, this supported linear rail and bearing block kit helps keep your gantry or sled tracking true while staying easy to service and integrate. Use it for CNC router machines, mills, lathes, laser engravers, trainer rocker plates, and other automated machines where smooth motion and solid support reduce wasted time on rework.
