High-rigidity crossed roller guide with V-V raceway configuration, providing multi-directional load capacity and micron-level positioning repeatability. Features hardened raceways and precision-ground rollers for minimal friction variation (±15% max). Includes mounting datum surfaces for simplified alignment.
- Semiconductor wafer handling robots
- 5-axis CNC rotary tables
- CT/MRI medical imaging sliding mechanisms
- Optical inspection equipment stages
- High-precision rotary indexers
Installation note:
Requires surface flatness ≤0.01mm/m and parallelism ≤0.02mm between rails.
Use 4.8-grade mounting screws torqued to 3.5N·m ±10%. Avoid sliding carriage
without lubrication - initial grease filling should cover 30-40% of raceway volume.
