Ultra-compact linear motion solution combining high rigidity with space-saving design. Features corrosion-resistant treatment and triple sealing for harsh environments. The dual-carriage configuration provides enhanced moment load capacity while maintaining smooth motion characteristics (friction coefficient ≤0.003). Includes mounting datum surfaces for precision alignment.
- Medical device positioning stages
- Semiconductor wafer handling robots
- High-speed PCB drilling machines
- Automated optical inspection (AOI) systems
- Desktop CNC milling platforms
Installation guidance:
Apply 4.5-5.5Nm torque during rail mounting. Use 0.02mm/m alignment tolerance for precision applications.
Avoid direct hand contact with raceway surfaces - residual skin oils accelerate wear.
