The SBR20 4000 WERB Supported Linear Rail is a precision linear motion component designed to provide stable and smooth guidance for long travel automation systems. Built with a supported round shaft mounted on an aluminum base, the SBR20 rail reduces shaft deflection over long distances and allows reliable motion in CNC machines, automation frames, and heavy sliding mechanisms. The 4000 mm length makes it suitable for large machines that require extended linear travel while maintaining rigidity and alignment.
Key Features
- Smooth and stable linear motion over long travel distances
- Supported rail design reduces shaft bending and vibration
- Strong aluminum base for better rigidity and mounting support
- Compatible with SBR20 linear bearing blocks
- Suitable for medium to heavy duty automation systems
Common Applications
Large CNC routers, laser cutting machines, woodworking machines, long travel automation systems, gantry machines, inspection tables, industrial automation frames, and custom motion platforms.
Selection Notes
Confirm the rail diameter (20 mm), rail length (4000 mm), and compatibility with SBR20 bearing blocks. Supported rails help prevent shaft deflection in long span systems. Ensure the mounting surface is flat and properly aligned to maintain smooth motion and avoid premature wear.
