Precision-engineered adjustable stroke cylinder featuring a unique mechanical stopper system for millimeter-level positioning accuracy. The dual chrome-plated piston rod and anodized aluminum body ensure corrosion resistance in humid environments. Integrated cushion adjustment screws allow fine-tuning of end-position deceleration.

Typical Applications:

• Precision workpiece positioning in CNC loading systems
• Variable height adjustment mechanisms in packaging lines
• Clamping force control in fixture applications
• Material feeding systems requiring stroke modification
• Automated door operation with variable opening width

Installation note: For optimal performance, maintain 0.3-0.5mm clearance between stopper and cylinder bracket during adjustment. Use locking compound on adjustment screws after final positioning. Requires 5μm filtered air with ≤5ppm oil content.

Adjustment Procedure:

1. Loosen both lock nuts on the stopper mechanism
2. Position stopper at desired stroke position using calibration marks
3. Torque lock nuts to 1.2N·m using a crowfoot wrench
4. Perform 3-5 test cycles to verify stroke stability
