Ultra-precision crossed roller guide featuring zero-backlash operation and high moment load capacity. The 4-row 45° contact angle design ensures equal load distribution across all rollers. Hardened running surfaces (HRC58+) provide exceptional wear resistance for long-term accuracy retention. Includes integrated scrapers that automatically remove debris from guide surfaces.
- High-speed CNC coordinate measuring machines
- Semiconductor wafer handling robots
- Precision optical alignment stages
- Medical CT scanner gantry systems
- Lithography equipment positioning systems
Installation requirements:
Requires mounting surface flatness ≤0.01mm/m and parallelism ≤0.02mm between rails.
Use 4.8-grade mounting screws torqued to 5.2N·m ±10%. Avoid sliding blocks without rail engagement.
Maintenance note:
Relubricate every 6 months in normal conditions (monthly in high-humidity environments).
Use only ISO VG22-class grease to maintain warranty coverage.
