Mahle adds new polymer coating to its bearing range


Mahle has applied a new polymer coating to its bearing range, enabling reduced friction as well as greater seizure resistance and boundary lubrication properties.

The recently developed polymer coating with melamine cyanurate can improve bearing characteristics in combustion engines. Thanks to the low friction coefficient, due to a multilayered structure, melamine cyanurate has unique lubrication properties. This enables quicker transition of the bearing to a hydrodynamic lubrication region.

At the same time, melamine cyanurate has a high thermal stability, ensuring robust operation of the bearing under conditions of inadequate lubrication. This enables a 20% increase in the load limit at which the bearing shell starts to seize.

“The new polymer coating is a good example of how the continuous optimization of the combustion engine can contribute to reducing emissions,” said Dr Andreas Pfeifer, head of product development engine systems and components at Mahle.
