High-rigidity crossed roller guide with V-type raceway design for simultaneous absorption of radial and axial forces. Features zero-backlash operation through precision roller preload adjustment (0.02-0.05mm). The hardened stainless steel construction (HRC58-62) ensures corrosion resistance in Class 4 environments.
- High-precision CNC rotary tables (4th/5th axis)
- Semiconductor wafer handling robots
- Medical CT scanner gantry systems
- Optical measurement equipment stages
- 3D metal printing rotary platforms
Installation requirements:1. Surface flatness ≤0.01mm/m
2. Parallelism between rails ≤0.02mm
3. Use M6×12mm SHCS bolts (12.9 grade) at 5.5Nm torque
4. Relubricate every 500km travel or 6 months (whichever comes first)
Avoid lateral impact forces exceeding 30% of static load capacity.
Use protective covers in environments with abrasive particles >5μm.
