We generally differentiate between compression rings and oil control rings. The key task for both ring types is to mutually seal off the combustion chamber and crankcase.
- Sealing against combustion gases
- Heat dissipation
- Scrape off and spread oil
Inertia and gas loads, as well as high temperatures, place high technical demands on piston rings. Optimum durability and compliance with emissions regulations are only achieved by tailoring piston rings precisely to the particular engine.
Motorservice supplies a customer-oriented, comprehensive product range with over 1,100 different ring sets for more than 8,000 applications.
Molybdenum-coated piston rings offer maximum temperature resistance with excellent emergency running properties.
Chromium-plated piston ring sliding surfaces reduce the wear on the interacting sliding parts and increase durability.
These coatings consist of a chromium layer with a network of cracks, into which firmly anchored hard materials – ceramic or micro-diamonds – are embedded.
