For oil cylinder seals, I believe everyone will not be unfamiliar with them, because we have been explaining the knowledge of this product all along, so that everyone can achieve the expected learning goals and requirements, thus making great gains and progress, and continuously benefiting from learning. So, in the coming time, this work will continue and will not stop.

Is there a distinction between primary sealing structure and auxiliary sealing in oil cylinder seals?

The oil cylinder seal includes a main sealing structure and auxiliary sealing. For the main sealing structure, commonly used ones include combination seals and Yx seals. For auxiliary seals, there are dust seals and static seals, so they can be selected and matched according to specific needs.

Why do oil cylinders need to be sealed? For oil cylinder seals, which parts of the oil cylinder are they generally used in?

The purpose of sealing the oil cylinder is to avoid the problem of internal leakage caused by communication between chambers, and thus cannot push the piston in the oil cylinder to move. Therefore, sealing operations should be carried out to avoid this problem. For oil cylinder seals, they are generally located at the piston of the oil cylinder and at both ends of the oil cylinder, mainly in these two parts.

Is there any deviation in the sealing ring of the oil cylinder seal during installation and other processes? Is this normal? In addition, how to disassemble the Y-shaped sealing ring?

The sealing ring in the oil cylinder seal will have a certain degree of shrinkage during processing, but due to its elasticity, as long as the sealing ring is in the correct specification and model, even if there is a deviation, it can be ignored.

For the disassembly of Y-shaped sealing rings, it can be done from both ends. However, for the convenience of operation, the disassembly work is usually started from the end closer to the sealing ring. So, there is no high difficulty in disassembling this type of oil cylinder seal.
