Ultra-compact linear guide system engineered for space-constrained precision applications. Features corrosion-resistant hardened rails (HRC58-62) and optimized ball circuit design achieving ≤25dB noise levels at 0.5m/s. Includes factory-applied lithium-complex grease compatible with most industrial environments.
- High-speed PCB depaneling machines (requires ≤5μm positioning repeatability)
- Medical analyzer slide mechanisms (compatible with sterilization protocols)
- Semiconductor wafer inspection stages (vibration-damped version available)
- Collaborative robot end-effector guidance (low-particle generation design)
- Optical lens coating equipment (vacuum-compatible up to 10-3 Pa)
Installation protocol:
Maintain 0.02mm/m alignment tolerance during rail mounting.
Use 4.4Nm torque for M4 mounting screws with Loctite 243.
Perform 30-minute run-in at 0.3m/s before full-load operation.
