High-precision crossed roller guide offering exceptional moment load resistance and minimal elastic deformation. Features alternating V-shaped raceways that eliminate clearance through controlled preload. The hardened steel construction ensures 20,000+ km service life under proper lubrication. Requires hardened mounting surfaces (≥HRC50) for optimal performance.
- Semiconductor wafer handling robots (cleanroom compatible)
- 5-axis CNC rotary/tilt tables
- Coordinate measuring machine (CMM) Z-axis guidance
- High-speed laser cutting head positioning
- Precision optical alignment stages
Installation criticals:
Mounting surface flatness ≤0.01mm/m, use 4.8 grade screws torqued to 2.0N·m in crisscross pattern.
Avoid side mounting - arrow mark on block indicates load direction.
