Ultra-precision crossed roller guide featuring 45° contact angle design for simultaneous radial and axial load capacity. The alternating orthogonal roller arrangement achieves near-zero clearance motion with ≤3μm repeatability. Hardened raceways and optimized roller crowning prevent edge stress concentration. Includes integrated oil reservoirs in carriage for extended maintenance intervals.
- High-speed CNC grinding machine Z-axis positioning
- Semiconductor wafer inspection stages
- 5-axis robotic arm rotary joints
- Optical lens coating equipment
- Coordinate measuring machine (CMM) slides
- Medical CT scanner gantry systems
Installation requirements:
Requires mounting surface flatness ≤0.01mm/m and roughness Ra0.8.
Use torque wrench for 2-step tightening sequence (50% → 100% of 8.8Nm).
Avoid side mounting without vertical support structure.
