Ring , Iran

A piston ring is a circular component mounted on piston grooves that seals the combustion chamber and controls oil flow. Diameter in industrial engines ranges from 60 to 150 mm, with thickness between 1.5 and 3.5 mm. It is typically made of hardened steel with coatings such as nitriding, chromium, or molybdenum for high wear resistance and low friction. Precisely machined grooves ensure complete sealing and minimize combustion gas leakage.

Piston rings include compression and oil control types, with oil grooves returning excess oil to the crankcase. Heat treatment such as surface hardening and stress relief increases fatigue life and thermal resistance. Installation uses a controlled clearance of 0.02–0.05 mm to accommodate thermal expansion at high temperatures. This design reduces oil consumption, increases engine efficiency, and improves piston performance in heavy gasoline and diesel engines.You can order and buy Ring from Iran by contacting us through whatsaap and email.
