The LGC4R28 features staggered roller arrangement with 45° contact angles, delivering ±30% higher moment rigidity than conventional linear guides. Its oil-wedge design maintains smooth motion under shock loads. The hardened raceway undergoes deep cryogenic treatment for enhanced wear resistance in contaminated environments.
- High-speed CNC grinding machine Z-axis guidance
- Semiconductor wafer handling robots
- Precision optical stage positioning systems
- Automated 3D measurement equipment
- Medical CT scanner gantry movement
Installation protocol:
Requires mounting surface flatness ≤0.01mm/m. Use 4.8-grade bolts torqued to 2.5N·m in cross-sequence pattern.
Avoid welding near rails - keep 150mm clearance zone. Run-in period: 50 cycles at 20% rated load before full operation.
