With increasing temperatures, pressures and speeds, piston rings are subjected to ever greater stresses. Concepts for less wear, less friction, improved sealing, and a higher fracture resistance are called for. MAHLE offers a solution. Their rings are produced from cast iron and steel using the latest technologies—and optimized in their performance with electroplated, thermal-sprayed or other new coatings. MAHLE piston rings are equipped for every requirement: whether for reducing the flank wear, longer service intervals, better conformity to the cylinder, reducing oil consumption, or reducing friction.
