High-rigidity cross roller guide with optimized stress distribution design, featuring alternating orthogonal roller arrangement for omnidirectional load capacity. The hardened raceway surface and chromium-plated rollers achieve C3-grade precision (JIS B1514). Includes built-in oil grooves for centralized lubrication systems.
- High-speed CNC rotary tables
- Semiconductor wafer handling robots
- Optical measurement equipment Z-axis stages
- Precision grinding machine indexing units
- Medical CT scanner gantry rotation mechanisms
Installation note:
Requires surface flatness ≤0.01mm/m and mounting base hardness ≥50 HRC.
Use 4.9-6.9 N·m torque for M6 mounting screws with Loctite 243 threadlocker.
Run-in with ISO VG68 grease for initial 50km travel distance.
