HGR20 Linear Guide Rail Kit with Ballscrew for CNC Machines

Get smoother, more precise motion in your CNC builds without the noise or instability.

This linear guide rail kit keeps your machine running steady, accurate, and consistent—even under demanding use.

Precision motion that keeps your projects accurate

✅ Achieve smoother movement that improves cutting and positioning accuracy

✅ Reduce vibration and noise for cleaner operation and better results

✅ Handle demanding loads with 25.31 static load rating for stability

✅ Maintain consistent motion with low friction and minimal wear over time

✅ Save setup time using pre-drilled M4 x 16 mm mounting holes

✅ Build reliable CNC systems with hardened steel components (up to HRC62)

The HGR20 linear rail system combines guide rails, slide blocks, and a ballscrew to create controlled, linear motion. As the ballscrew rotates, the nut moves smoothly along the rail, translating motor power into precise movement. This makes it ideal for CNC routers, mills, and automated machinery that depend on accuracy.

Constructed from GCr15 bearing steel with chrome-plated surfaces, the rails resist wear and corrosion while maintaining rigidity. The system runs with low noise and minimal deflection, helping you produce cleaner cuts and more consistent results across repeated tasks.

Available in multiple lengths from 700 mm to 2000 mm, this kit adapts to different machine sizes and project requirements. Each set includes rails, slide blocks, a ballscrew, ball nut, and BF12/BK12 support, giving you a complete setup ready for installation.

Compared to basic rail systems, this setup delivers tighter control and smoother travel, reducing the small inconsistencies that can affect machining quality. The pre-matched components also simplify assembly and reduce adjustment time.
