SBR12 Linear Rail Kit 1000mm with 4 Bearing Blocks for CNC

Achieve smooth, stable motion in your machine builds without unwanted vibration or noise. This SBR12 linear rail kit gives you controlled movement you can rely on for precise work.

Built for automation setups, it keeps your system aligned and running consistently, even under continuous use.

Stable motion that improves accuracy and machine performance

✅ Maintain precise movement with 1000mm supported rails that reduce deflection

✅ Achieve smoother travel with low-friction bearing blocks for consistent operation

✅ Handle demanding setups using steel rails and rigid aluminum support

✅ Run quieter systems with reduced vibration during motion

✅ Save setup time with a complete kit including 2 rails and 4 sliding blocks

✅ Use across multiple machines like CNC routers, lathes, and automation systems

This linear motion system includes two 39 in (1000 mm) SBR12 rail shafts and four SBR12UU bearing blocks that slide smoothly along the rails. The internal linear bearings reduce friction, helping your machine move cleanly and consistently during operation.

The combination of carbon steel rails, bearing steel components, and aluminum alloy support keeps the structure stable while resisting wear. Chrome-plated surfaces help protect against rust while maintaining smooth travel over time.

Installation is straightforward. Align the rail and slide the blocks into position for a secure fit. Once mounted, the system requires minimal upkeep, making it suitable for both workshop builds and industrial setups.

Compared to unsupported rails or lower-rigidity systems, this setup minimizes flex and maintains alignment across the full 1000 mm length. That means better accuracy, less noise, and more reliable long-term performance in real working conditions.
