The through-rod design allows external stroke indication and mechanical locking. Integrated mounting slots enable multi-axis positioning in compact automation setups.
- Precision workpiece clamping in CNC fixture systems
- Variable height positioning in semiconductor wafer handling
- Force-controlled pressing operations in electronic assembly
- Adjustable stopper mechanisms in packaging lines
- Medical device testing equipment actuators
Installation protocol:
Mount on vibration-damped surfaces using Class 8.8 fasteners. For optimal performance:
- Align piston rod within 0.2mm perpendicular tolerance
- Maintain 50mm clearance for stroke adjustment access
- Use C-shaped spanner for stroke locking (3.5N·m torque max)
