Precision crossed roller guide featuring 45° angular contact design for simultaneous radial and axial load handling. The LGC3A75R13-H incorporates hardened raceways and ceramic-coated rollers (optional) for contamination resistance. Its compact profile enables high moment load capacity (Mx=180Nm, My=220Nm, Mz=240Nm) in space-constrained applications.
- High-speed CNC rotary tables (4th/5th axis)
- Semiconductor wafer handling robots
- Optical measurement equipment Z-axis stages
- Precision grinding machine column guides
- Medical CT scanner gantry rotation systems
Installation requirements:
Requires mounting surface flatness ≤0.01mm/m and parallelism ≤0.02mm between rails.
Use torque wrench (12-15N·m) for mounting bolts in crisscross sequence. Thermal expansion
compensation required for installations exceeding 1m length.
