Industrial-grade crossed roller guide featuring V-V raceway design for simultaneous load bearing in all directions. The compact profile combines high rigidity (2000N/μm) with smooth motion (friction coefficient μ=0.003). Preloaded rollers eliminate clearance while maintaining ±0.5μm running parallelism. Includes hardened stainless steel end seals and corrosion-resistant anodized aluminum carriage.
- High-speed CNC rotary tables (4th/5th axis)
- Semiconductor wafer handling robots
- Precision optical inspection stages
- Medical CT scanner gantry systems
- Automated fiber placement machines
Installation note:
Requires surface flatness ≤0.01mm/m and mounting base hardness ≥HRC50.
Apply lithium soap-based grease (ISO VG68) during assembly. Avoid angular
misalignment exceeding 0.02° to prevent premature wear.
