High-rigidity cross roller guide featuring 45° contact angle rollers for simultaneous load capacity in all directions. The alternating orthogonal roller arrangement eliminates clearance fluctuations, achieving ±0.005mm repeat positioning accuracy. Hardened raceways (HRC58-62) ensure extended service life under heavy moment loads.
- Precision rotary indexing tables in CNC machining centers
- Z-axis motion systems for semiconductor wafer inspection equipment
- High-speed pick-and-place robotic arms (SCARA-type)
- Optical lens alignment stages
- Medical CT scanner gantry movement
Installation note:
Requires mounting surface flatness ≤0.01mm/m and parallelism ≤0.02mm between rails.
Use torque wrench (2.0-2.5N·m for M5 screws) with Loctite 243 threadlocker.
Perform running-in: 10 cycles at 20% rated load before full operation.
