SBR 10-4000

The SBR10-4000 Linear Rail is a supported round shaft guide designed to provide stable, smooth linear motion over long travel distances in automation and mechanical systems. With a 10 mm precision shaft mounted on a rigid aluminum support base, this rail helps reduce shaft deflection while maintaining consistent movement for sliding blocks and linear bearings. It is commonly used in CNC machines, small automation frames, and DIY motion systems where long travel and reliable guidance are required.

Key Features

• Supported 10 mm precision shaft for improved rigidity
• 4000 mm long rail suitable for extended travel systems
• Smooth linear guidance when used with compatible SBR10UU blocks
• Reduced shaft bending compared to unsupported round rods
• Aluminum support base for easy mounting and alignment
• Compatible with many CNC and automation motion setups

Common Applications

CNC routers, 3D printers, linear gantries, pick and place machines, automation frames, robotics sliders, packaging machines, and DIY motion systems.

Selection Notes

Confirm compatibility with SBR10UU bearing blocks and ensure the mounting surface is straight and rigid. Long rails like 4000 mm should be properly supported along the entire base to maintain alignment and accuracy. Proper lubrication and clean operating conditions will improve bearing life and motion smoothness.
