SBR Linear Guide Rails Kit with 4 Bearing Blocks for CNC DIY

Achieve smooth, precise motion in every build. These SBR linear guide rails keep your CNC, router, or automation project moving cleanly and consistently.

Reduce vibration, minimize noise, and gain better control over every pass, cut, or slide.

Smoother motion for cleaner, more accurate results

✅ Move smoothly with built-in ball bearings that reduce friction and vibration

✅ Handle demanding loads with high-capacity support up to 980 N per block

✅ Maintain accuracy with precise hole spacing and straight shaft alignment

✅ Reduce noise during operation for a more controlled workspace

✅ Fit multiple builds with lengths from 800 mm to 2200 mm

✅ Improve stability with all-metal structure and secure slide locking

The kit includes 2 linear guide rails and 4 bearing blocks, giving you a complete motion system for DIY CNC machines, lathes, 3D printers, and more. The combination of carbon steel shafts and aluminum supports creates a stable base that keeps movement predictable and repeatable.

Each slide block uses internal ball bearings to glide along the rail with low resistance. This means less effort from your motor and fewer interruptions during operation. Whether you're engraving, cutting, or positioning components, motion stays consistent.

Pre-aligned mounting holes and standardized shaft sizes make installation straightforward. You spend less time adjusting and more time building or running your machine.

Compared to basic rail systems, this setup delivers smoother travel, better load handling, and more reliable long-term use without constant adjustment or maintenance.
