The dual anti-rotation guide mechanism prevents piston spin during operation, while the multi-lip seal design ensures ≤0.5 Nm breakaway friction. Includes magnetic piston for position sensing compatibility.
Industrial Applications:
- Die casting machine ejection force control
- Plastic injection molding clamp adjustment
- Automotive welding fixture positioning
- CNC machine tool workpiece retention systems
- Packaging line product height compensation
Installation guidelines:
Always degrease rod surface before use. Lubricate with ISO VG32 turbine oil.
For vertical mounting, install rod end downward to prevent seal wear.
Maximum side load: 180N at full extension.
Stroke Adjustment Protocol:
- Loosen both lock nuts (M16x1.5) using 24mm wrench
- Rotate adjustment screw (2mm pitch) for precision positioning
- Re-tighten nuts to 35±5 Nm torque
- Perform 5 full cycles to verify stroke stability
