High-rigidity cross roller guide featuring alternating orthogonal roller arrangement for exceptional moment load resistance. The 45mm wide rail utilizes full-complement needle rollers achieving ±5μm repeatability. Hardened raceways (HRC58-62) and optimized roller crowning ensure smooth motion under heavy cutting forces.
- Semiconductor wafer handling robots
- 5-axis CNC rotary tables
- Precision coordinate measuring machines (CMM)
- Medical CT scanner gantries
- Optical alignment stages for lithography
- High-speed pick-and-place units (>2m/s)
Installation requirements:
Mounting surface flatness ≤0.01mm/m, roughness Ra1.6. Use M6×12mm SHCS
(4.4-7.4Nm torque) at max 150mm intervals. Avoid welding sparks - thermal
distortion above 150℃ affects accuracy.
