Precision crossed roller guide engineered for ultra-stable linear motion in multi-axis systems. Features zero-backlash operation through controlled preload and hardened raceways with mirror finishing (Ra 0.2μm). The compact symmetrical design enables equal load distribution in all directions, making it ideal for rotary-to-linear motion conversion applications.
- Semiconductor wafer handling robots
- 5-axis CNC rotary tables
- Coordinate measuring machine (CMM) arms
- Photonics alignment stages
- High-speed pick-and-place units
- Medical CT scanner gantries
Installation note:
Requires mounting surface flatness ≤0.01mm/m. Use torque wrench (recommended 5.4N·m for M6 bolts)
with sequential tightening pattern. Perform laser alignment after thermal stabilization.
