High-rigidity crossed roller guide featuring X-axis/Y-axis integrated design with 45° contact angle rollers. The staggered roller arrangement eliminates clearance while maintaining smooth motion, achieving 3x higher moment load capacity compared to conventional linear guides. Hardened raceways utilize vacuum decarburization treatment for improved wear resistance.
- High-precision CNC rotary tables (4th/5th axis)
- Semiconductor wafer handling robots
- Optical measuring equipment Z-axis stages
- Heavy-duty laser cutting machine gantries
- Vertical machining center tool changers
Mounting requirements:
Requires mounting surface flatness ≤0.02mm/m and surface roughness Ra1.6.
Use M12x1.75 mounting screws torqued to 85-95N·m in cross pattern sequence.
Avoid welding sparks exposure which may anneal hardened surfaces.
