Precision crossed roller guide employing 90° orthogonal roller arrangement for exceptional moment load resistance. Features vacuum-compatible sealing and hardened raceways with mirror finishing (Ra 0.1μm). Requires parallelism ≤0.01mm/m on mounting surfaces. Includes pre-drilled M6 mounting holes at 50mm pitch.
- Semiconductor wafer handling robots
- 5-axis CNC rotary tables
- Coordinate measuring machine (CMM) stages
- Laser processing equipment Z-axis
- Optical lens alignment systems
Mounting protocol:
Apply 4-6Nm torque during installation using CR-V steel screws.
Avoid direct coolant exposure - use wiper kits (AKS-LGC-W1) in wet environments.
Relubrication interval: 500km travel or 12 months.
