Ultra-compact linear motion solution combining high rigidity with minimal footprint. Features corrosion-resistant construction and maintenance-free operation through integrated particle-resistant seals. The dual-block configuration provides enhanced moment load capacity while maintaining smooth motion characteristics. Requires alignment within 0.05mm/m for optimal performance.
- High-speed PCB component placement machines
- Medical analyzer probe positioning systems
- Semiconductor wafer inspection equipment
- Precision 3D printer X/Y axis mechanisms
- Laboratory automation sample handlers
Installation protocol:
Use torque-controlled installation (1.2-1.5N·m for M4 screws) with sequential
tightening pattern. Maintain rail straightness within 0.02mm using precision
alignment jigs. Apply ISO VG32 equivalent grease quarterly in dusty environments.
