Rock Solid SBR40 Linear Guide Rail Kit 2800mm 40mm Shaft With 2 Hella Smooth Sliding Bearing Blocks For CNC Routers And Custom Builds Featuring Durable Aluminum Housing And Worry Free Plastic Inner Runners

Premium SBR40 Carbon Steel Linear Guide System
✔️ Includes 2800mm chrome coated rail with two 40mm slide blocks

You get a complete linear motion setup for your custom machinery build. This kit pairs one long carbon steel shaft with twin sliding housings for steady movement. You will mount it directly onto router frames or CNC tables to handle heavy loads without flex. The plastic internal runners glide quietly through wood dust and metal chips.

✅ Full 2800 millimeter carbon steel guide shaft with hard chrome finish
✅ Two aluminum alloy slider housings rated for continuous heavy duty travel
✅ Engineered plastic inner wheels eliminate loose steel balls and prevent jamming
✅ Sealed design shuts out workshop debris and resists moisture buildup
✅ Fast bolt on mounting pattern fits standard machine frame cutouts

💡 How do you choose the right shaft diameter for a custom spindle carriage? You should select a sturdy forty millimeter rail when your tool head carries heavy cutting forces down long travel paths. This handy linear track system gives you solid support without taking up extra bench space.

- A hardened steel rod maintains tight tolerance while resisting bending during fast feeds

- Oxidized aluminum carriages grip the axle firmly while absorbing vibration from router bits

- Polymer bushings slide past sawdust and grit without requiring regular lubrication changes

- Extended twenty eight hundred millimeter length eliminates mid run wobble on oversized frames
