Precision crossed roller guide system featuring high rigidity and minimal elastic deformation under moment loads. The staggered 90° roller arrangement provides equal load distribution in all directions, achieving 2.5x higher moment resistance compared to conventional linear guides. Integrated oil grooves enable continuous lubrication for maintenance-heavy environments.
- Semiconductor wafer handling robots
- 5-axis CNC machining center rotary tables
- Coordinate measuring machine (CMM) Z-axis mechanisms
- High-precision optical alignment stages
- Lithium battery stacking equipment
Installation guidance:
Requires surface flatness ≤0.01mm/m and mounting surface roughness Ra1.6μm.
Use 4.8-grade mounting screws torqued to 14.7N·m with Loctite 243.
Avoid particle contamination during assembly - Class 1000 clean environment recommended.
