piston ring

The Piston Ring is a metal ring that fits inside the piston groove. There are two types of piston rings: the compression ring and the oil ring. The compression ring can be used to seal the combustible mixture in the combustion chamber; the oil ring is used to scrape excess oil from the cylinder. The engine brand that we have as following:Cummins, Perkins, Mitsubishi, Caterpillar,VOLVO, Komatsu,Isuzu, Yanmar,Hitachi, DEUTZ, Yuchai, Shangchai, Weichai and so on.

Piston seals maintain sealing contact in sliding motion between the piston and cylinder bore for hydraulic and pneumatic equipment. The piston seal is a shaft seal, and the piston rod seal is a hole seal. The oil cylinder is composed of a cylinder block, a piston, a piston rod, a cylinder head and a sealing ring. When using a piston seal, it can be used in combination with an anti-pollution seal to prevent damage due to foreign matter or adiabatic compression, which can improve durability.
