High-rigidity cross roller guide with 90° V-groove design for multi-directional load capacity. Features hardened raceways and alternating orthogonal roller arrangement that achieves near-zero backlash. Includes alignment marks for simplified installation and tapped mounting holes for tool-free adjustment.
- Semiconductor wafer handling robots
- CNC coordinate measuring machines (CMM)
- Precision grinding machine Z-axis
- Laser cutting head positioning systems
- Medical CT scanner gantry movement
Installation note:
Requires surface flatness ≤0.01mm/m and use of torque wrench (recommended 2.6N·m for M6 bolts).
Perform parallel alignment using master rail method for multi-slide systems.
Critical parameters:
Maintain 0.5-1.5% lubricant film thickness ratio. Avoid axial misalignment exceeding ±0.05°
during dynamic operation to prevent edge loading.
