Ultra-compact linear motion solution combining high rigidity and smooth movement through hardened steel rails and precision-ground balls. Features corrosion-resistant coatings and multi-stage sealing for contaminated environments. The S10 precision class enables micron-level positioning repeatability, while the double flange block design prevents rotation under moment loads.
- High-speed PCB component placement machines
- Laser cutting head positioning systems
- Medical diagnostic slide rail mechanisms
- 3D printer X/Y axis motion systems
- Semiconductor wafer inspection equipment
Installation Notes:
Requires mounting surface flatness ≤0.01mm/m. Use torque-controlled tightening (0.8-1.2Nm for M4 screws).
Avoid cantilevered loads exceeding 1:3 ratio. Relubricate every 100km travel or 6 months in clean environments.
