Beefed-Up SBR20 Linear Rail Kit 3000mm Set With Four 1500mm Rails, Eight SBR20UU Bearing Blocks, Dowel Pins And Adjustment Handles For DIY CNC Routers And Automated Machines

Beefed-Up SBR20 Linear Rail Kit 3000mm Set with 4x1500 Rails
✔️ Includes 4x1500mm rails, 8x SBR20UU blocks, dowel pins and handles

The beefed-up SBR20 rail kit is a complete linear motion system designed for DIY CNC routers, lathes, laser welders, and automated machines. It combines four 1500mm rails (4x1500mm, 59 in) with eight SBR20UU bearing blocks for smooth, precise travel along a 3000mm span when extended with dowel pins.

✅ 4 x 59 in / 1500 mm rails with dowel-pin holes
✅ 8 x SBR20UU bearing blocks for smooth, precise carriage
✅ 4 x dowel pins to extend rails from 1500mm to 3000mm
✅ 2 x adjustment handles to tune slider tightness for fine control
✅ 32 x M6x20 screws for mounting blocks and plates

💡 What is a handy use for a SBR20 linear rail kit in a DIY CNC build?

It’s handy for improving rigidity and motion precision on hobby CNCs. - Pillow block bearings stabilize the rail and keep the gantry aligned - SBR20 rails provide smooth, low-friction guidance for repeatable cuts - The kit includes essential hardware to extend from 1500mm to 3000mm
