Two Pack 800mm SBR20 Linear Rail Kit With 4 SBR20UU Bearing Blocks, 31.5 Inch Guide Rails, Locking Handle And M6 Screws, A Pro Grade DIY CNC Sliding System Built For Rock Solid, Smooth, Accurate Motion
✔️ Two 800mm rails with 4 SBR20UU blocks, locking handle, M6 screws
This two-pack 800 mm linear rail kit includes two SBR20 rails, four SBR20UU bearing blocks, one locking handle, 16 M6 x 20 screws (M6 x 0.79 in) and a wrench. Built for accuracy, it delivers smooth, low-friction motion ideal for DIY CNC machines, precision measuring setups, and automated projects. The metal bearings and open housing design resist wear far better than plastic guides, while the main axle and aluminum support frame stabilize the rail for rock-solid performance.
✅ 2 x SBR20 800 mm rails (31.5 in) for long strokes
✅ 4 x SBR20UU bearing blocks for smooth, precise motion
✅ 1 locking handle to adjust slider tension
✅ 16 x M6 x 20 screws (M6 x 0.79 in) plus a wrench for quick assembly
