- Plastic injection molding machine core pulls
- Heavy material handling gates/doors
- Industrial press brake tooling actuators
Installation tip:
Allow minimum 3mm thermal expansion gap during mounting. For vertical installations,
use locknut (ASNU12) to prevent piston rod rotation. Lubricate rod weekly with ISO VG32
hydraulic oil in high-cycle applications (>500 cycles/hour).
