- Plastic injection molding machine core pulls
- Automotive assembly line clamping devices
- Foundry equipment door actuators
- Palletizing robot end-effector drives
Installation note:
Maintain parallel alignment of load path and cylinder axis. For vertical mounting,
use locknut retention on piston rod threads. Perform monthly cushion adjustment checks
in high-cycle applications (>500,000 cycles/year).
