What will happen to non-standard automatic cylinders? Those places are easy to break down. How to prevent and repair them? Thank you.

The common fault is that the telescopic rod and sealing ring of the cylinder are damaged, resulting in air leakage.

Prevention: Pay attention to the filtration of compressed air, ensure the purity of air source, and add special oil for cylinder to the filter regularly.

Also, it depends on what brand of cylinder is used. A good brand of cylinder is quite durable.
