High-rigidity roller guide system featuring crossed cylindrical rollers arranged at 90° angles, providing equal load capacity in all directions. The optimized raceway geometry minimizes stress concentration while maintaining <0.003mm/m alignment accuracy. Includes hardened steel scrapers to prevent debris ingress in harsh environments.
- Semiconductor wafer handling robots
- Precision grinding machine Z-axis
- Medical CT scanner gantry movement
- Optical measurement equipment stages
- High-speed PCB drilling machines
Installation requirements:
Requires mounting surface flatness ≤0.01mm/m and parallelism ≤0.02mm between rails.
Tighten M6 bolts in cross pattern at 5.5N·m torque. Thermal expansion compensation
needed for installations exceeding 1m length.
- Use with AKN series servo motors for closed-loop positioning
- Optimal performance with AirTAC MQL20 mini linear scale
- Compatible with ISO VG32 hydraulic oil environments
