Ultra-compact linear guide system featuring high rigidity and smooth motion characteristics. The triple-seal design (S10AH) provides IP54-level contamination resistance while maintaining low friction coefficient (μ<0.003). Precision-ground raceways ensure ±0.05mm/m straightness accuracy.
- High-speed PCB drilling/spindles
- Medical analyzer slide mechanisms
- Semiconductor wafer handling robots
- Precision 3D printer X/Y axes
- Laser cutting head positioning
Installation note:
Requires mounting surface flatness <0.02mm/100mm. Use M4×8mm flat-head screws
(torque 1.6N·m) at max 80mm intervals. Relubricate every 100km travel
with AKT-A2 grease.
