Piston Rings

Grindlays Engine Parts Pvt Ltd stands ahead amongst the leading piston ring manufacturers in India. It helps perform incredible combustion and reduced oil consumption in the engines. By offering premium quality mechanical products, we are recognized as the credible supplier of piston rings in India and across the world. To ensure the high-quality and best performance, we offer a complete range of engine parts manufactured of Grey Cast Iron, Alloyed Cast iron, Spheroidal Graphite Iron and High Strength Steel. This material possesses excellent heat and wear-resisting quantities inherent in its graphitic structure. We offer an extensive range of products ensuring thousands of applications in any engine. Some of the prime applications are racing, automotive, heavy-duty transportation, agriculture, small engine, industry and much more.

Piston rings are produced for the maintenance of the cylinder and combustion pressure of an automobile. Their actual role lies in the prevention of oil from seeping into the combustion chamber and sealing in the air and fuel to compress them. Piston rings from Grindlays come as three rings and they are performing different functions helping the engine in its operation. The top ring, second ring and oil ring are three rings that are simultaneously used in the piston.

The top ring is the first ring also known as the compression ring. It helps the sucker perform well during the combustion process thus, preventing it from losing any pressure. It helps maintain the building of pressure when the sucker reaches the top of the stroke and all this is possible because it acts as a barrier.

Also known as the secondary ring, the second ring is a backup compression ring with a slightly tighter tolerance thus, helping the top compression ring in sealing the combustion chamber.

The oil ring is the last ring that functions along with the sucker inside the engine in lubrication of cylinder, walls, suckers, rings and wrist pins. It prevents the oil from the combustion process and also helps in thermal control by cooling the piston and directing oil around it.

Life and size of Piston Rings

The number of piston rings will vary depending on the size of the engine. The life of a piston ring entirely depends on the piston ring type, the size of the engine it is fitted on, and the operational condition of the ring and the liner. The steel piston rings are more durable than ductile iron rings, and ductile iron rings are more durable than cast iron rings.

Types of Piston Rings:

Plain Compression Rings, Scrapper/Napier Rings, Slotted Oil Rings, Hard Chrome Plated Compression & Oil Rings, Taper Faced(Periphery) Rings, Full/ Half Keystone Rings, Step Cut Rings, Slant Cut Rings, Lock Type Rings, Spring Loaded Oil Rings (with Helical Coil springs), Profile Grinded Oil Rings, Duaflex Oil Rings, Steel Laminated Segments, 3-Piece Nifflex Oil Rings (various designs), Steel Oil Rings, Bimetal Rings etc.
