  • Product Details
  • Company Profile

The functions of the piston ring include four functions: sealing, regulating oil (oil control), heat conduction (heat transfer), and guiding (support).

The piston ring is a metal elastic ring with a large outward expansion deformation, which is assembled into the corresponding annular groove of the cross section. Reciprocating and rotating piston rings rely on the pressure difference of gas or liquid to form a seal between the outer circular surface of the ring and the cylinder and one side of the ring and the ring groove.
