Installation and Maintenance
Installation
Mount the cylinder securely using recommended brackets based on application needs.
Connect pneumatic tubing ensuring clean, dry air supply to prevent contamination.
Install magnetic sensors in the dedicated slot to enable position feedback, if needed.
Adjust cushion valves for optimum cushioning—avoid fully open or fully closed positions to prevent damage.
Perform leak tests and operational checks after installation.
Maintenance
Regularly inspect rod seals, cylinder barrel, and piston rod for damage or rust.
Replace seals when air leakage exceeds allowable limits to maintain performance.
Lubricate rod seal and grooves with recommended grease during seal replacement.
Keep the external surfaces clean to prevent dust buildup and wear.
Follow manufacturer recommendations for disassembly and reassembly during maintenance.
Avoid operating beyond specified pressure and temperature limits to prevent premature failure.
