Linear Guide Rail Set, SBR16 1500mm, 2 Rails 4 Blocks

Linear guide rail set SBR16 1500mm delivers smooth, accurate linear motion for CNC routers and automation builds. This 59 in (1500 mm) kit combines two supported rails with four SBR16UU bearing blocks to reduce stutter, improve repeatability, and handle demanding loads. A chrome-plated carbon steel shaft with an aluminum base helps resist corrosion, while pre-machined mounting holes speed alignment for DIY machines, 3D printers, laser engravers, mills, and lathe sleds.

• Includes 2× 59 in/1500 mm SBR16 supported rails plus 4× SBR16UU slide blocks for complete linear motion setup


• Delivers smooth, low-friction travel with ball bearings to reduce chatter and uneven movement


• Improves accuracy and repeatability with precise shaft straightness for stable CNC and router carriage motion


• Handles higher loads with supported rail design; rated 774 N dynamic and 1180 N static per block


• Simplifies installation with accurate mounting holes for fast alignment on automated machines and DIY frames

Built for makers who need reliable linear rails and bearings without rework, this supported SBR rail system helps keep your gantry or sled tracking true under load. Use it to upgrade or replace worn motion components on CNC machines, laser engravers, 3D printers, trainer rocker plates, and other high-load automation projects. Check your required travel length, mounting spacing, and carriage size before ordering to ensure fit. Grab yours today and get your next build moving smoothly.
