What is the difference between piston sealing ring and cylinder piston rod sealing ring?

Now we are understanding, what is piston seal? What is a piston rod seal? Before, Sunway Pneumatic tells you what a piston and piston rod are? The piston is a reciprocating part in the automobile engine cylinder block. The piston rod is a connecting component that supports the work of the piston. It is mostly used in oil cylinders and cylinder motion execution components. It is a moving component with frequent movements and high technical requirements. Let us take a closer look atcylinder There are seals between the piston and the piston rod What's the difference?

The biggest difference is that the piston sealing ring is a shaft sealing ring, while the piston rod sealing ring is a hole sealing ring. The oil cylinder is composed of cylinder block, piston, piston rod, cylinder head and sealing ring. The piston sealing ring (Figure 1 is the structural diagram of the piston sealing ring) refers to the sealing between the cylinder and the piston. If the sealing is not good, it will affect the performance of the oil cylinder. The sealing groove is opened on the piston. Piston rod seal (Figure 2 shows CylinderPiston rod seal Structure diagram) refers to the space between the piston rod and the cylinder head If the sealing is not good, oil will leak. The sealing groove is opened in the hole.
