Ultra-compact linear motion solution combining high rigidity with space-saving design. Features staggered ball circuit pattern for smooth operation (≤45dB noise level) and dual-lip seals with dust-resistant SCR2 scrapers. The AP preload ensures minimal deflection (≤0.01mm) during high-speed reciprocation up to 2m/s.
- Precision optical lens positioning systems
- PCB depaneling machine X-Y stages
- Medical pipette array mechanisms
- Semiconductor wafer inspection equipment
- Desktop CNC engraver Z-axis assemblies
Installation guidance:
Maintain 0.02mm/m alignment tolerance during mounting. Use torque-controlled tightening (0.8-1.2N·m for M3 screws)
in cross pattern sequence. For vertical installations, apply supplemental lateral support every 150mm.
