Industrial-grade cross roller guide featuring 45° contact angle design for simultaneous radial and axial load capacity. The LGC3A series incorporates hardened raceways with vacuum-degassed steel construction, achieving positioning repeatability ≤±2μm. Integrated oil retention grooves and centralized lubrication ports enable maintenance intervals up to 5,000 operating hours.
- High-precision CNC rotary tables (4th/5th axis)
- Semiconductor wafer handling robots
- Optical grinding machine Z-axis positioning
- Automated coordinate measuring machines (CMM)
- Heavy-duty laser cutting gantry systems
Installation requirements:
Requires mounting surface flatness ≤0.01mm/m and parallelism ≤0.02mm/m.
Use torque-controlled tightening sequence (12Nm for M8 bolts) with Loctite 243 threadlocker.
Run-in period: 50 cycles at 20% rated speed before full-load operation.
