High-precision adjustable stroke cylinder featuring dual-side position sensing slots and precision machined piston rod. The SAIJ series incorporates a unique "position memory" mechanism allowing repeatable stroke adjustment without re-calibration. The anodized aluminum construction provides corrosion resistance in humid environments.

Typical Applications:

• Variable height positioning in automated assembly lines
• Clamping force adjustment in CNC fixture systems
• Packaging machines requiring stroke customization
• Pharmaceutical equipment needing oil-free operation
• Plastic injection molding ejector systems

Installation note: For optimal performance, maintain 0.3-0.5mm clearance between cylinder body and mounting surface. Use locknuts (not included) on adjustment screws after stroke setting. Lubricate guide shafts every 500km of travel.

Stroke Adjustment:

1. Loosen both locknuts on the adjustment screws
2. Rotate screw clockwise to decrease stroke (max 5mm per full rotation)
3. Counter-clockwise rotation increases stroke
4. Tighten locknuts to 1.2-1.5 N·m torque after adjustment
