High-precision crossed roller guide with X-axis/Y-axis combined load capacity, featuring vacuum-compatible design and minimal lubrication requirements. The 45° V-groove roller arrangement ensures zero backlash operation and compensates for mounting surface parallelism errors up to ±0.1mm. Includes integrated wipers and grease retention grooves.
- Semiconductor wafer handling robots
- Precision optical alignment stages
- Medical CT scanner gantry systems
- High-speed PCB drilling machines
- Lithography equipment linear motion systems
Installation protocol:
Requires surface flatness ≤0.01mm/m and roughness Ra0.8 mounting base.
Use 0.05mm feeler gauge during alignment. Torque M5 screws to 3.5N·m
in crisscross pattern. Initial lubrication with ISO VG32 grease.
