High-rigidity crossed roller guide featuring orthogonal cylindrical rollers arranged at 90° angles, delivering ±0.5μm/m positioning repeatability. The LGC4R25's compact profile combines X/Y axis constraint capability with 4-direction equal load characteristics, making it ideal for space-constrained precision mechanisms.
- High-speed CNC rotary index tables
- Semiconductor wafer inspection stages
- Optical lens grinding equipment
- Robotic joint articulation modules
- Coordinate measuring machine (CMM) Z-axis mechanisms
Installation requirements:
Requires mounting surface flatness ≤0.01mm/m and roughness Ra1.6.
Use torque-controlled tightening sequence (2.5-3.0N·m for M5 screws).
Avoid angular misalignment exceeding 0.05° during assembly.
