- Press-fit operations with depth control requirements
- Packaging line product height compensation systems
- Semiconductor handling equipment with Z-axis adjustment
- Plastic injection molding ejection force control
 Installation tip: 
            Engage the stopper lock nut with 12-15Nm torque after position adjustment. 
            For vertical installations exceeding 45° angle, specify the optional rod-end support bracket (SAI-AS50).
