Ultra-rigid crossed roller guide featuring 90° V-groove design for simultaneous radial and axial load handling. The LGC2A75R16-H achieves near-zero backlash through controlled preload adjustment, making it ideal for multi-axis precision systems. Includes hardened stainless steel end caps for debris protection.
- 5-axis CNC rotary/tilting tables
- Semiconductor wafer handling robots
- Coordinate measuring machine (CMM) Z-axis stages
- High-speed laser cutting rotary units
- MRI machine component positioning systems
Installation note:
Requires mounting surface flatness ≤0.02mm/m. Use 4.5-5.5Nm torque for M8 fasteners.
Avoid sliding blocks during transit - rail ends must be aligned within 0.1mm during assembly.
