- Automotive assembly line clamping devices
- CNC machine tool workpiece positioning
- Food processing conveyor gate actuators
- Printing press paper feed mechanisms
Installation guidelines:
Maintain 0.5mm minimum alignment tolerance between rod end and load.
For vertical mounting, use M3x6 set screws to secure mounting feet.
Allow 100mm clearance at rod end for maintenance access.
