High-precision crossed roller guide featuring 90° V-groove design for simultaneous radial and axial load handling. The staggered roller arrangement eliminates clearance while maintaining smooth motion characteristics. Includes hardened running surfaces with mirror-finished raceways (Ra≤0.2μm) for reduced friction and enhanced durability. Compatible with automatic lubrication systems through integrated grease nipples.
- High-speed CNC rotary tables (4th/5th axis)
- Semiconductor wafer handling robots
- Precision optical alignment stages
- Medical CT scanner gantry systems
- Coordinate measuring machine (CMM) Z-axis guides
Installation Protocol:
Requires surface flatness ≤0.01mm/m and mounting surface roughness Ra1.6 or better.
Use 4.5Nm torque for M5 mounting screws with Loctite 243 threadlocker.
Avoid direct coolant exposure - install protective bellows if used in wet environments.
