Professional-grade crossed roller guide featuring ultra-high rigidity and minimal elastic deformation (≤3μm under max load). The staggered 90° roller arrangement provides omni-directional load capacity. Includes preload adjustment shims (0.02mm increments) for eliminating backlash. Compatible with ISO 10285-1 lubrication ports.
- High-speed CNC grinding machine Z-axis positioning
- Semiconductor wafer handling robots
- Precision optical inspection equipment
- 5-axis machining center rotary tables
- Lithography machine stages
Installation protocol:
Requires granite surface plate alignment (flatness ≤0.01mm/m) and 12.9-grade mounting bolts torqued to 45N·m in cross pattern sequence. Thermal compensation recommended for environments with >2℃/m temperature gradients.
