- Adjustable height platforms for automated assembly lines
- Material handling systems requiring programmable stroke lengths
- Packaging machinery with variable product sizes
- Plastic injection molding ejection mechanisms
 Installation note: 
            Ensure proper alignment of guide rods during mounting. Use locknuts (included) 
            to secure adjustment screws after positioning. Lubricate through integrated 
            grease nipple every 50,000 cycles with ISO VG32 hydraulic oil.
