MAHLE Original can claim to be the largest manufacturer of piston rings in the world today.
This stability results in a tremendous foundation for research and development, which guarantees that MAHLE Original is the highest performing ring in both performance and light vehicle applications.
The largest manufacturer of piston rings in the world, MAHLE Original piston rings lead the way in ring technology and innovation for the Aftermarket.
MAHLE Original rings are at the forefront of piston ring technology for light vehicles.
Extensive OE connections mean that MAHLE Original rings possess the technological edge.
Innovations such as the CP-20 oil ring, narrow compression rings, steel compression rings for gasoline engines, low-tension oil rings, and coated compression rings for diesels all originated from the OE.
The MAHLE Original performance line consistently proves that it should be the ring of choice under every hood, regardless of the application.
Traditionally, grey cast iron or ductile iron was the material of choice for automotive applications; however, today, steel is increasingly preferred over iron by many engine builders.
Steel compression ring technology has been utilized in heavy-duty applications for over 30 years.
This expertise has become essential to the design and engineering of modern automotive engines.
Steel piston rings provide higher tensile strength, higher yield strength, greater fatigue life, and greater hardness while still maintaining a lower ring mass.
These factors contribute to better stress resistance, reduced groove pound-out, longer service life, better conformability, superior oil economy, and improved blow-by control while also lowering friction.
