SBR20 1000mm Linear Rail Kit With Four Precision Slides
✔️ Includes 2 carbon steel guides four aluminum sliders with screws

This SBR20 linear guide kit pairs two full-length shafts with four heavy-duty carriage units to deliver steady back-and-forth motion for machinery projects. Shop owners and maker space crews typically mount these assemblies on DIY CNC routers, 3D printers, laser cutters, and X-Y positioning tables to replace wobbly lead screws. The aluminum alloy heads lock onto hardened steel rods for zero play, letting operators swap out worn rails without recalibrating entire frames. You get everything needed to drop right into existing brackets using standard M6 fasteners.

✅ Two-piece 1000mm high-carbon steel shaft guides resist bending under heavy cuts
✅ Four SBR20UU double-row ball bearings roll smoothly across polished rods
✅ Hardened bearing steel inner races reduce friction during rapid tool changes
✅ Pre-drilled aluminum carriage bases snap over shafts for quick field swaps

💡 How do precision linear slide units prevent vibration during heavy metal milling operations?
These guided track assemblies cancel wobble by splitting weight across dual bearing rows.
Hardened cross-contacts grip the shaft firmly while making maintenance handy for shop techs.
Standard metric hole patterns fit common extrusion channels without custom drilling or shims.
