Ultra-compact linear motion solution combining high rigidity with space-saving design. Features hardened steel rails (HRC58+) and optimized ball circuit geometry for smooth motion consistency. The corrosion-resistant anodized block includes integrated mounting threads (M3×0.5) for simplified integration. Compatible with cleanroom environments due to particle containment seals.
- Precision optical lens positioning systems
- PCB drilling/spindle Z-axis mechanisms
- Medical pipette arm assemblies
- Semiconductor wafer inspection stages
- Desktop CNC router gantry systems
Mounting recommendation:
Ensure rail parallelism within 0.05mm/m using precision level during installation.
Use torque-controlled driver (0.4-0.6N·m) for M3 mounting screws to prevent block deformation.
