Piston Rings Manufacturers & Suppliers in India

piston rings manufacturers Grindlays is a recognized name among Piston Ring Suppliers in the Automotive Industry for supplying high quality Piston rings. Our piston rings have proven their capability to provide efficient combustion and reduce oil consumption in the engines. A piston ring is a simple ring on a piston that seals the gap between the piston and the cylinder wall. Piston Ring Manufacturers generally produces piston rings that are made of cast iron alloy or a high strength steel material which is reinforced with tin, copper or chrome. The rings should be capable enough to withstand temperatures of upto 300 degree Celsius inside an internal combustion engine and facilitate heat dissipation. Our Piston rings are made to help in heat dissipation, seal the combustion gases for improved engine power and hence better fuel efficiency.
There are three basic objectives that piston rings that they need to achieve depending on their placement on the piston.
The first ring or primary ring also called as the compression ring assists in preventing the gas from leaking out during the combustion process. The second ring or secondary ring assists the primary ring in keeping the pressure intact. The third ring also known as oil rings assists in keeping the engine cool by dissipating the oil around it. Each of these three rings have to work together optimally to give the combined functionally and a good output.
