High-precision adjustable stroke cylinder with dual cushion control, featuring a built-in stroke adjustment lock mechanism for stable positioning. The anodized barrel resists corrosion in humid environments, while the triple-lip rod seal ensures minimal leakage. Requires 5μm filtered air (ISO 8573-1 class 4) for optimal performance.

Typical Applications:

• Variable height positioning in assembly lines
• Press machine stroke control systems
• Packaging equipment with adjustable clamping force
• Automated warehouse stacker height adjustment
• Plastic injection molding ejector mechanisms

Installation tip: For vertical mounting exceeding 45° angle, install a mechanical lock (sold separately) to prevent unintended stroke changes. Allow 15mm clearance around adjustment screws for maintenance access.

Stroke Adjustment:

1. Release air pressure from both ports
2. Loosen lock nut using 8mm wrench
3. Rotate adjustment screw (1 full turn = 2mm stroke change)
4. Re-tighten lock nut to 12-15N·m torque
5. Perform test cycle at low pressure before full operation
