To check for cylinder leaks, you can use soapy water. If bubbles appear at the outlet of the front cover piston rod, it indicates that the U-ring is no longer effective. Additionally, if the cylinder is connected to the front or rear cover, make sure that the roll is properly seated between the cylinder and the cover. If this isn’t the case, the seal may not be functioning correctly, and the component might not meet the required standards.

If the cylinder is leaking, it could mean that the COP seal has failed. The QGAW10 cylinder assembly uses a rolling process during manufacturing, which makes it impossible to repair once damaged. Therefore, if any leakage is detected, the entire unit must be replaced rather than repaired.

It's important to perform regular inspections to ensure proper function and prevent unexpected failures. In industrial settings, maintaining hydraulic systems is crucial for safety and efficiency. Always follow the manufacturer’s guidelines when checking or replacing parts. If you're unsure about the condition of the cylinder, it's best to consult a professional technician to avoid further damage or potential hazards.
