Innovation from the outset: the first light-alloy piston in 1921 served as the prelude to MAHLE’s success story with the combustion engine—many more innovations were to follow... As a development partner to the international automotive and engine industry and a top-3 systems supplier, you will find us in every second road vehicle today.

Pistons

  • As the world’s largest manufacturer of pistons, MAHLE is intensively researching the products of tomorrow and already offers solutions for al- most every engine today—fast, reliable, and around the globe. With our pistons, aftermarket customers receive original equipment engine parts and thus the guarantee that comes with all of our products: tried and tested under the most gruelling conditions and proven in prac- tice. A promise you can count on.

Valve Componants

  • Valves form a closed system together with valve seat inserts and valve guides, which has to withstand extremely high stresses. For that reason, our product range includes not only valves but also their tribological partners: valve seat inserts and valve guides. The combined development of these products in one system brings considerable advantages in terms of minimizing wear and increasing economic efficiency.

Piston Rings Sets

  • As a leading manufacturer of pistons, we are con- stantly improving the performance and running properties of our piston rings—our state-of-the-art production facilities set quality standards. Dec- ades of development and production guarantee an efficient interplay between pistons and piston rings for the highest demands.

Turbochargers

  • Exhaust gas turbochargers are a key technology for increasing performance and reducing fuel consumption and emissions. MAHLE is a long- standing business partner to international automobile and engine manufacturers in the development and production of heavy-duty turbocharger components.

Cylinder Liners

  • We are also constantly improving our cylinder surfaces. The precise matching of the honed cylinder liners with the pistons and piston rings (through optimized cast iron surfaces) lowers oil consumption and reduces blow-by, resulting in less wear, shorter run-in periods, and longer running times. MAHLE produces cylinder liners for many international engine manufacturers for both series production and the aftermarket and always according to the same strict quality standards for material, structure, and surface quality.

Thermostats

  • MAHLE Aftermarket offers a variety of thermo- stats and components for regulating temperature: expansion elements, thermostat inserts, thermal switches, and thermocouples, as well as integrated, housing, and sleeve valve thermo- stats, transmission oil and EGR thermostats, and map-controlled thermostats.

Bearings

  • In cooperation with engine manufacturers, we develop and test bearings for every single engine type. Ongoing fundamental research and development of materials and production technologies guarantees the highest quality fatigue-resistant, adaptable, highly resilient, and resistant to wear and corrosion. We supply bearing shells, flanged bearings, bushings, and thrust washers with diameters from 27 to 140 mm, as well as bushings with diameters from 6 to 105 mm.

Filters

  • MAHLE Aftermarket offers a variety of thermo- stats and components for regulating temperature: expansion elements, thermostat inserts, thermal switches, and thermocouples, as well as integrated, housing, and sleeve valve thermo- stats, transmission oil and EGR thermostats, and map-controlled thermostats.
