High-rigidity crossed roller guide with V-shaped raceway design for multi-directional load support. Features vacuum-compatible construction and ultra-low friction coefficient (μ<0.003). The hardened stainless steel rollers provide 30% higher moment stiffness compared to conventional ball guides. Includes pre-loaded clearance adjustment shims for precision alignment.
- Semiconductor wafer handling robots
- Medical CT scanner gantry systems
- Precision optical alignment stages
- High-speed CNC tool changers
- 3D metal printing Z-axis mechanisms
Installation note:
Use torque-controlled tightening (1.2N·m max for M4 screws) with parallelism within 0.01mm/m.
Avoid thermal expansion by acclimatizing to operating temperature for 2 hours before installation.
