High-rigidity crossed roller guide featuring 90° V-type raceway design for simultaneous radial and axial load handling. The staggered roller arrangement eliminates clearance while maintaining smooth motion (friction coefficient μ=0.003-0.005). Includes hardened raceways (HRC58-62) and pre-loaded rollers (±0.01mm pre-tension adjustment).
- High-precision CNC rotary tables
- Semiconductor wafer handling robots
- Optical measurement equipment stages
- Medical CT scanner gantries
- Aerospace component test fixtures
Installation note:
Requires mounting surface flatness ≤0.01mm/m and parallelism ≤0.02mm.
Use 4.9-6.9N·m torque for M6 mounting screws. Avoid welding sparks near
the rail surface during integration.
