High-rigidity cross roller guide system featuring 90° V-groove design for simultaneous control of radial and axial loads. The LGC4B series utilizes alternating orthogonal rollers to achieve near-zero backlash and exceptional moment load resistance. Includes pre-lubricated sealed carriages with anti-creep design for vertical applications.
- High-speed CNC rotary tables (4th/5th axis)
- Semiconductor wafer handling robots
- Precision optical alignment stages
- Medical CT scanner gantry systems
- Automated coordinate measuring machines (CMM)
- Lithography equipment positioning systems
Installation guidance:
Requires surface flatness ≤0.01mm/m and parallelism ≤0.02mm between rails.
Torque mounting bolts to 5.4N·m ±10% in crisscross pattern.
Perform running-in at 20% max speed for 50 cycles before full operation.
