Ultra-compact linear motion solution combining high rigidity with minimal installation space. Features chrome-plated rails for corrosion resistance and hardened bearing surfaces for extended service life. The optimized ball circuit design reduces vibration during high-speed operation, making it ideal for precision positioning systems requiring smooth motion characteristics.
- Medical device XYZ stages (CT scanners, DNA sequencers)
- Semiconductor wafer handling robots
- Desktop CNC engraving machines
- Automated optical inspection (AOI) equipment
- 3D printer gantry systems
- Laboratory automation slide mechanisms
Installation note:
Requires mounting surface flatness ≤0.02mm/m. Use torque-controlled screwdriver
(0.7-0.9Nm for M4 screws) to prevent rail deformation. For full-length rails >400mm,
maintain 0.5mm thermal expansion gap at rail ends.
