Precision-adjustable pneumatic cylinder featuring dual-position locking mechanism for mid-stroke fixation. The SAUJ50 series combines 360° adjustable magnetic field detection slots with an anti-rotation guide design, enabling millimeter-level positioning accuracy. Special hardened stainless steel guide rings ensure smooth operation under side load conditions.

Industrial Applications:

• Variable position clamping in CNC machining centers
• Adjustable stopper mechanisms in assembly lines
• Position-controlled material handling systems
• Packaging machine pusher arms with variable product sizes
• Textile machinery tension adjustment devices

Installation guidance: Maintain 0.5mm minimum clearance between magnetic sensor and cylinder body. Lubricate piston rod weekly with ISO VG32 hydraulic oil. Avoid welding spatter exposure - install protective sleeve if used near fabrication areas.

Stroke Adjustment Protocol:

1. Lock position by tightening adjustment bolt clockwise
2. Release air pressure before adjusting stroke length
3. Use 4mm hex key for fine-tuning (max torque 1.2N·m)
4. Verify position with limit switches after adjustment
