Product Characteristics
Product Advantage
The piston ring is made of high-strength materials and has undergone special treatment to achieve high surface hardness and good wear resistance. This can reduce friction with the cylinder wall and extend the service life of the piston rings.
Product Features
The piston rings have good sealing performance, they are fixed on the piston and form a seal between them and the cylinder wall. When the piston moves up and down, the piston ring can effectively prevent high-pressure gas leakage generated by combustion in the cylinder, ensuring normal engine operation.
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.
