Professional-grade crossed roller guide featuring V-V raceway configuration for equal load distribution in all directions. The LGC1B50R19-H combines high moment stiffness (35kN·m/rad) with ultra-smooth motion (friction coefficient <0.003), making it ideal for multi-axis systems requiring micron-level positioning stability. Integrated debris-resistant seals maintain lubrication integrity in ISO Class 5 cleanroom environments.
- Semiconductor wafer handling robots
- 5-axis CNC grinding machine rotary tables
- Photonics alignment stages
- Coordinate measuring machine (CMM) Z-axis columns
- Lithography equipment precision slides
Installation guidance:
Requires granite surface plate calibration during mounting (flatness ≤0.01mm/m²).
Torque mounting bolts to 4.5N·m ±10% using cross-pattern sequence.
Avoid angular misalignment exceeding 0.05° during assembly.
