Ultra-high rigidity crossed roller guide with 45° V-groove design for multi-directional load capacity. Features chromium-plated rails and precision-ground rollers achieving ≤1μm surface roughness. Optimized for applications requiring micron-level stability under combined loads (radial, reverse, and moment forces). Includes anti-creep mechanism for vertical installations.
- Semiconductor wafer handling robots
- 5-axis CNC rotary/tilting tables
- Coordinate measuring machine (CMM) Z-axis
- High-precision optical alignment stages
- Medical CT scanner gantry systems
Installation note:
Requires 0.01mm/m alignment accuracy during mounting. Use torque wrench (2.0-2.5 N·m)
for fasteners and perform full-length parallelism check with dial indicator. Avoid thermal expansion
by matching rail/material CTE with host machine.
