- Automotive assembly line positioning mechanisms
- Packaging machinery ejection/pushing operations
- Industrial automation with position feedback requirements
- Plastic injection molding machine auxiliary controls
Installation note:
Maintain proper rod alignment during mounting – maximum allowable lateral load 35N.
Requires regular lubrication (ISO VG32 hydraulic oil recommended).
For stroke lengths >500mm, use intermediate support brackets to prevent rod deflection.
