Two Pack Linear Guide Rails SBR12 SBR16 SBR20 With Four UU Shaft Bearing Blocks For CNC Builds Smooth Glide Motion 250mm 300mm 1000mm Lengths Complete DIY CNC Kit

Two Pack Linear Guide Rails and UU Bearing Blocks for CNC
✔️ Two rails and four UU blocks in 250mm, 300mm, or 1000mm options

This two-pack kit pairs high-precision linear guide rails with four UU bearing blocks to create a stable, smooth-moving guide system. It’s designed for CNC builds, DIY routers, and automation rigs where precise travel across 250-1000 mm is needed.

✅ 2 rails and 4 UU bearing blocks included
✅ Rails sizes SBR12/SBR16/SBR20 with lengths 250mm, 300mm, or 1000mm
✅ Made from bearing steel with surface hardening for wear resistance
✅ Dual-axis design provides stable support for heavy loads and higher speeds

💡 What is a linear guide rail and bearing block set used for in CNC builds?

It's a handy, precise motion system for guiding components along a straight axis.

- precise motion along a straight axis - low friction for smooth operation - compatible with SBR12/SBR16/SBR20 rails and UU blocks - ideal for DIY CNC kits and automation rigs ✝️
