High-rigidity crossed roller guide featuring V-V raceway configuration for equal load distribution in all directions. The LGC4B series combines high moment resistance (30% greater than standard models) with smooth motion characteristics, achieved through precision-ground raceways and staggered roller arrangement. Includes corrosion-resistant black oxide coating and anti-creep end caps.
- High-precision rotary table indexing systems
- Semiconductor wafer handling robots
- Optical inspection equipment Z-axis stages
- Medical CT scanner gantry mechanisms
- 5-axis CNC tool changer positioning
Installation note:
Requires surface flatness ≤0.01mm/m and parallelism ≤0.02mm between rails.
Tighten mounting screws in crisscross pattern at 3.5-4.5N·m torque.
Perform initial re-lubrication after 100km of travel.
