- Plastic injection molding machine ejectors
- Steel coil handling systems
- Paper mill roller positioning
- Foundry equipment door actuators
Installation note:
Use flexible couplings to compensate for misalignment (max 0.5° angular deviation).
For vertical mounting, install speed controller on lower port to prevent piston slam.
Lubricate every 5 million cycles in continuous operation.
