- Plastic injection molding machine ejectors
- Material handling lift gates
- Packaging machine pusher systems
- Automotive welding fixture positioning
Installation note:
Ensure proper rod alignment (<0.5° angular misalignment) and use supported mounting brackets for vertical installations.
For stroke adjustment, turn cushion needle valves clockwise in 1/4 increments while testing.
