Ultra-compact linear motion solution combining high rigidity and smooth movement through precision-ground rails and 4-row ball bearing design. Features corrosion-resistant hardened surfaces (HRC58-62) and anti-creep preload adjustment (N2 class). Optimized for space-constrained automation with 0.002mm/m alignment tolerance requirements.
- Semiconductor wafer handling robots
- Medical diagnostic slide mechanisms
- High-speed PCB component placement machines
- Desktop 3D printer X/Y axis systems
- Optical lens positioning stages
Installation note:
Requires mounting surface flatness ≤0.01mm/100mm. Use torque-controlled tightening
(1.2-1.5N·m for M3 screws) in cross pattern. Avoid thermal expansion by allowing
0.5mm clearance per meter at >25℃ environments.
