- Large-format CNC router tool changers
- Steel coil handling equipment actuators
- Plastic injection molding machine clamp units
- Solar panel production line positioning
Installation note:
Requires rigid mounting surface with flatness ≤0.1mm/m². For vertical installations,
use auxiliary rod support brackets when stroke exceeds 800mm. Lubricator recommended
for extended service life in high-cycle applications (≥500,000 cycles/year).
