Premium Butter Smooth Linear Motion Guide Rail Kit Featuring Double Axis Roller Ball Bearings Sgr15 Ninety Inch Tracks Paired With Sgb15 Four Wheel Sliders For Zero Drag Cnc Upgrades And Pro Builds

Premium double axis linear motion rail kit for CNC rigs
✔️ Includes four 90 inch rails paired with SGB15 roller wheels

This heavy duty guide rail system moves your build components smoothly along tight paths. You mount the U channel tracks to your workbench frame and slide the wheels into place. It works great for laser cutters, xy tables, and custom automation projects that demand quiet travel. The double axis roller bearings load evenly across both steel rods. You get buttery slides for rapid tool changes and precise cuts. Every piece ships ready to bolt onto your existing frame without extra drilling.

✅ Four SGR15 extruded aluminum tracks measuring 2300 mm or 90.55 inches each provide long travel range.
✅ Compact SGB15 roller blocks feature sealed ball bearings that spin freely without extra friction.
✅ Eccentric bushing adjustments let you dial in exact play levels for crisp edge cuts.
✅ Chrome plated steel shafts resist rust while anodized aluminum seats keep weight down.

💡 How do you properly tension linear slide units for maximum longevity on cnc routers? Dial the tension rings until the carriage rolls straight for a handy, reliable setup. - Adjust the eccentric bushings until the slider glides without noticeable side shake. - Keep the rails clean from metal chips and dust particles before each run. - Lubricate the shafts lightly with standard machine oil every few months.
