High-rigidity crossed roller guide with X-axis/Y-axis simultaneous constraint capability, featuring 45° V-groove roller arrangement for moment load resistance. The hardened steel construction ensures 20% higher stiffness than conventional linear guides. Includes anti-creep design for vertical applications.
- Semiconductor wafer handling robots
- Coordinate measuring machine (CMM) Z-axis
- Precision optical alignment stages
- High-speed CNC tool changers
- Lithium battery stacking machines
Installation criticals:
Requires mounting surface flatness ≤0.01mm/m and parallelism ≤0.02mm between rails.
Use 4.5Nm torque for M5 mounting screws with Loctite 243 threadlocker.
Avoid lateral impact during handling -
Use protective covers when stored. Break-in period: 50 full-stroke cycles at 0.1m/s
before full-speed operation.
