Precision miniature linear guide optimized for space-constrained automation, featuring hardened raceways and anti-creep design. The N2 preload ensures minimal deflection during high-speed reciprocation while maintaining smooth motion. Integrated dust-proof structure with steel-reinforced seals extends maintenance intervals in particle-rich environments.
- High-speed PCB component placement machines
- Semiconductor wafer inspection stages
- Medical analyzer reagent arms
- Desktop CNC engraving systems
- Automated optical measurement equipment
Installation note:
Requires mounting surface flatness ≤0.02mm/m. Use torque-controlled tightening
(1.2-1.5N·m for M4 screws) in cross pattern. Relubricate every 100km travel
using AKT-A2 grease through side ports.
