    Product Characteristics



    Basis Information


    The piston ring ensures a seal between the piston and the cylinder wall, preventing gas and lubricating oil leakage. Forming a lubricating film to reduce metal to metal friction between the piston and cylinder wall. Forming a lubricating film to reduce metal to metal friction between the piston and cylinder wall.


    Product Principle


    The piston rings also help reduce friction between the piston and the cylinder wall. When the piston reciprocates up and down, it is in close contact with the cylinder wall. Without the presence of piston rings, direct metal to metal friction can lead to energy loss and excessive wear.

    The piston rings are located in the grooves at the top and bottom of the piston, in close contact with the cylinder wall. During the working process, the piston ring forms a closed sealing chamber between the piston and the cylinder wall through its own elasticity and shape design.


    The piston ring is generally composed of several rings, closely connected on both sides. Common structures include oil rings, oil control rings, and upper and lower spiral grooves. The piston rings with different structures undertake different functions, such as sealing the cylinder, conducting heat, lubricating, etc.
