- Foundry equipment door actuators
- Palletizing robot end-effectors
- Industrial press feeding mechanisms
Installation note:
Maintain parallel alignment of piston rod with load direction. For vertical mounting,
use mechanical locknuts on piston rod thread. Lubricate every 3,000km of stroke
movement under normal conditions.
