Ultra-compact linear motion solution combining high rigidity with minimal space requirements. Features hardened raceways (HRC58-62) and precision-ground surfaces (Ra0.4μm) for smooth operation. The dual-carriage design enables stable load distribution, while the integrated wiper system maintains cleanliness in critical environments. Requires periodic relubrication every 100km travel or 6 months.
- High-speed PCB component placement machines
- Medical analyzer slide rail systems
- Semiconductor wafer inspection equipment
- Desktop CNC engraving platforms
- Automated microscope focusing mechanisms
Mounting guidance:
Ensure rail parallelism ≤0.02mm/m using precision level. Tighten mounting screws
in crisscross pattern with 2.5N·m torque. Avoid side loading exceeding 15% of C.
