- Automotive welding fixture positioning
- Injection molding machine core pulls
- Heavy material handling gates/doors
- Paper mill roller positioning
Installation notes:1. Use locknuts with 120-150Nm torque for mounting
2. Maintain 0.5-1mm clearance between rod end and load during alignment
3. For vertical installations, always use rod-end support brackets
4. Adjust cushion screws gradually (1/4 turns) during commissioning
