Linear Guide Rail Set, 2x1000 mm Rails, 4 Slide Blocks

Linear guide rail set SBR16 1000mm delivers smooth, accurate motion control for CNC routers, 3D printers, laser engravers, and DIY automation builds. This kit pairs 2 x 39.4 in (1000 mm) supported rails with 4 SBR16UU bearing blocks to reduce friction, handle heavy loads, and improve repeatability. Chrome-plated carbon steel shafts and an aluminum base help resist corrosion while maintaining stable alignment under pressure.

• Includes 2 x 1000 mm SBR16 supported rails and 4 x SBR16UU slide blocks for complete linear motion setups


• Delivers smooth, low-noise travel with built-in ball bearings for consistent sliding without stutter


• Handles high loads with up to 774 N dynamic and 1180 N static capacity per block for rigid, stable motion


• Improves precision with straight, accurately sized 16 mm shafts for repeatable positioning


• Simplifies mounting with pre-drilled, accurate holes for faster alignment on CNC and automation frames

Upgrade your motion system with supported linear rails built for rigidity, accuracy, and long service life. The carbon steel shaft and aluminum support base keep your gantry or sled steady, while the bearing blocks glide with low friction to reduce missed steps and uneven cuts. Ideal for router/mill/lathe sleds, CNC machines, 3D printer axes, and trainer rocker plate builds. Grab yours today and finish your build with stable, predictable linear movement.
