The LGC2A150R25-H features a compact symmetrical design with optimized roller contact angles, delivering ±0.5μm/m positioning repeatability. Its double-row 45° crossed roller configuration provides equal load capacity in all directions, making it ideal for multi-axis systems requiring minimal elastic deformation. The hardened raceways and precision-ground rollers ensure smooth motion with friction coefficients below 0.003.
- High-speed CNC rotary tables (4th/5th axis)
- Semiconductor wafer handling robots
- Optical measurement equipment stages
- Precision grinding machine slides
- 3D printing gantry systems
Installation note:
Use torque-controlled tightening (recommended 5.5N·m for M6 screws) and perform parallel alignment
within 10μm/m. Relubricate every 100km of travel using ISO VG32-grade grease.
